Glossary

A listing of Buddhist concepts, ancestors and Bodhisattvas, from the book Finding Your Seat: A Zen Handbook.

Anattā

 

See under Three Dharma Seals

 

Aniccā

 

See under Three Dharma Seals

 

Bhikkhu, Bhikkhunī

 

A traditionally ordained celibate male (bhikkhu) or female (bhikkhunī) monastic, pledged to following the approximately 227 bhikkhu or 311 bhikkhunī precepts (numbers vary in different traditions), which are found in the sacred texts known as the Vinaya.

Bodhicitta

 

The aspiration to awaken for the sake of helping sentient beings; this impulse is central to the teachings of the Mahāyāna. Bodhicitta is further divided into ‘relative bodhicitta’, the cultivation of loving-kindness and compassion for others, and ‘ultimate bodhicitta’, the cultivation of non-dual wisdom or seeing into the Emptiness of all phenomena, that is, that nothing exists apart from anything else. These two, compassion and wisdom, are seen as equally necessary elements of awakening.

 

Bodhidharma
(d. 543?)

 

The legendary founder of the Zen (Chan) School. Known as the twenty-eighth Indian ancestor, Bodhidharma is said to have brought the practice and teaching of Zen from India to China (see further under Chan below). He is famous for his fierce and uncompromising approach to practice and teaching, typified in reports of his initial encounter with the Chinese Emperor Wu (quoted below), of his sitting and facing a wall in a cave at Shaolin without speaking for nine years, and in the legend of his cutting off his eyelids to prevent himself from falling asleep while meditating. It is said that as the eyelids hit the ground, the first tea plants sprang up. The first koan in the Hekiganroku begins as follows: Emperor Wu of Liang asked the Great Master Bodhidharma, ‘What is the first principle of the holy teachings?’ Bodhidharma said, ‘Emptiness without holiness.’ The Emperor said, ‘Who is standing before me?’ Bodhidharma replied, ‘I don’t know.’ The Emperor did not understand. Bodhidharma’s reply of ‘I don’t know’ has been called the most famous response in Zen; Zen practice continually throws each of us back on our own not-knowing.

 

Bodhisattva

 

A bodhisattva is anyone in whom the spirit of bodhicitta has arisen, and who has therefore taken a vow to achieve enlightenment for the sake of all beings. In the Theravāda tradition in particular, ‘the Bodhisatta’ refers to the Buddha during the years (and lifetimes) before he had attained his Complete Perfect Enlightenment. In the Mahāyāna tradition, many great, archetypal Bodhisattvas are venerated, such as Kannon (Avalokiteśvara), the Bodhisattva of Compassion; Mañjuśrī, the Bodhisattva of Wisdom; and Samantabhadra, the Bodhisattva of Skillful Means or Enlightened Action. Additionally, however, the Zen teaching is that each of us who sincerely makes the effort to walk in the path of the Buddha is also a Bodhisattva.

Brahmavihārā

 

‘Divine Abode’. One of the four qualities that the Buddha taught which, when cultivated, can create a heaven-on-earth within and around us, namely: loving-kindness, compassion, joy at the happiness of others, and equanimity.

 

Buddha

 

Literally, ‘the one who is awake’, Buddha is a word used by Shakyamuni when he was asked to explain who he was. In the Mahāyāna view, Shakyamuni, the Buddha of our own age, is only one of countless billions of awakened Buddhas who populate the universe offering support to sentient beings. The word can also be used to refer to the awakened nature of the universe which is inherently present within each one of us. See also under Three Jewels.

 

Chan

 

The word ‘Zen’ is the Japanese form of the Chinese word ‘Chan,’ which is, in turn, the Chinese form of the Sanskrit (Indian) word ‘Dhyāna’ meaning ‘meditation’ or ‘concentration’. In the Buddha’s teaching, Dhyāna is one of the eight essential aspects of the path to liberation (see under Eightfold Path), and the Chinese Chan school of Buddhism is the one that put special emphasis on this aspect of the practice. The evolution of the word Dhyāna to Chan and then to Zen follows the historical path of the teachings as they moved from India to China and Korea and then to Japan. Bodhidharma brought this school of Buddhism to China in the fifth century, and it reached Japan in the twelfth century.

Daisan

 

Private interview offered by a senior student rather than a teacher.

 

Dāna

 

‘Giving,’ the first of the Paramitas. Colloquially, ‘dāna’ is often used to refer to donations to a Dharma Centre or to a teacher, priest or monastic, and in particular to the food offerings of the laity upon which monastics depend for their sustenance, as they do not handle money.

 

Dependent Co-Arising, or Dependent Origination

 

See under Pratītyasamutpāda.

Dhammapada

 

One of the most beloved of the Pali Sūttas, the Dhammapada consists of a series of gāthās, or verses, which pithily express the core teachings of the Buddha.

 

Dharma

 

The teachings of the Buddha, the Law of the universe, or simply ‘the way things are’ (which is what the teachings of the Buddha reveal); dharma (with a small ‘d’) is most often used in the plural (dharmas) to mean ‘things, phenomena, the stuff of our physical and non-physical world’. See also under Three Jewels.

 

Dharma Heir

 

One designated by their teacher in a public ceremony as having embodied the transmitted teaching and as having the aptitude, spiritual maturity and upright character required to teach others effectively.

Dōgen Zenji (Zen Master Dōgen)

 

The founder of the Japanese Sōtō Zen School who lived from 1200—1253 (see under Sōtō and Rinzai). As a young man, Dōgen trained under Rinzai Masters Eisai and Myōzen, then travelled to China where he studied Chan with Master Rujing. After returning to Japan he established the Sōtō school at Eihei-ji temple. He was a prolific writer, and his written works are still studied intensively, both by Zen practitioners and by religious historians, as masterpieces of Zen expression.

 

Dokusan

 

The Japanese word dokusan means literally to ‘go alone’, and in Zen training it refers to a one-to-one meeting between a teacher and student.

 

Dukkha

 

Suffering, unsatisfactoriness. A possibly false but oft-quoted etymology makes the word ‘dukkha’ refer to an axle-hole that is not properly fitted to its axle. In other words, dukkha encompasses not just the more obvious types of pain and loss, but also the way that our lives and circumstances so often feel off-kilter or in need of fixing. The Buddha delineated three types of suffering, related to the Three Dharma Seals: the suffering of suffering (painful physical and emotional experiences), the suffering of change (impermanence), and the existential suffering of being. The last stems from our sense of separation or alienation – our belief in our own independent existence.

Eightfold Path

 

The Way to liberation as taught by the Buddha. In his first discourse the Buddha set out eight aspects of the path to liberation, usually translated as follows: Right View, Right Thought, Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness, Right Concentration. “Right” however, is not the best translation of the original Sanskrit word samyak whose meaning is closer to “complete.”

 

Emptiness (Śūnyatā)

 

The teaching that all things are empty of a separate self or of an absolute, independent, or eternal existence. From the positive perspective this is the doctrine of Pratītyasamutpāda or Interbeing. Insight into emptiness is a goal both of practice and of Madhyamaka philosophy and the Prajñāpāramitā Sūtras. The great Indian teacher Nāgārjuna was instrumental in the development of these last two. See also under Bodhicitta.

 

Four Noble Truths

 

The Four Noble Truths are: the truth of suffering, the truth of the causes of suffering, the truth of the cessation of suffering, and the truth of the way out of suffering. Though these truths have long been referred to in English as the Noble Truths, an equally valid or perhaps preferable translation would be Ennobling Truths. This captures the way in which these truths may act upon us when we start to live by them. (See further the Wikipedia article on the Four Noble Truths under ‘Truths for the noble ones’.)

Four Sights

 

An old person, a sick person, a corpse, and a monk in meditation: these are the sights Prince Siddhartha (the future Buddha) saw on his first journeys outside of the palace grounds where he had been raised. His encounter with the and universality of suffering led to his renunciation of his life of luxury and quest for enlightenment.

 

Four Vows (or Four Bodhisattvic Vows)

 

These four vows of the bodhisattva are recited at the end of each formal sitting:

All beings without number I vow to liberate,

Endless blind passions I vow to uproot,

Dharma gates beyond measure I vow to penetrate,

The Great Way of Buddha I vow to attain.

 

Harada, Daiun Sogaku (1871–1961)

 

See under Sōtō and Rinzai.

Heart Sūtra

 

Probably the most frequently recited sūtra of Mahāyāna Buddhism, this brief text expresses the essence of the Prajñāpāramitā (Perfection of Wisdom) teachings on Emptiness.

 

Hekiganroku

 

The Blue Cliff Record is a koan collection compiled by Xuedou Chongxian (980–1052; Setchō in Japanese). It was later commented upon by Yuanwu Keqin (1063–1135; Engo in Japanese). Though chronologically an earlier collection than the Mumonkan, it is generally the second book of koans taken up by students in dokusan.

 

Interbeing

 

See under Pratītyasamutpāda.

Jukai

 

The ceremony in which one formally enters on the Buddhist Path. The heart of the ceremony is the taking of the sixteen Precepts. Practitioners participate in this ceremony not just once, but on a regular basis, as a way of renewing their vows and affirming an ongoing commitment to ethical conduct.

 

Kannon

 

The Bodhisattva of Compassion. See Bodhisattva.

 

Kapleau, Rōshi Philip (1912–2004)

 

Founder of the Rochester Zen Center and author of the Zen classic The Three Pillars of Zen as well as many other books. For more information see AZC Teachers and lineage.

Karma

 

In English the word ‘karma’ is generally used as a shorthand for ‘karma-vipāka’ or action-result. Buddhism teaches that all things exist dependent on causes and conditions, and, moreover that our own actions are causes of future conditions.

 

Kinhin

 

Walking meditation.

 

Kjolhede, Rōshi Bodhin (1948– )

 

Current Abbot of the Rochester Zen Center. Dharma Heir of Rōshi Kapleau and teacher of Amala-sensei. For more information see AZC Teachers and lineage.

Kōan

 

A kōan is a Zen teaching story. The word ‘kōan’ is the Japanese form of the Chinese ‘gong an’, a term that comes from Chinese law, where it means a ‘public case’ or precedent. Kōans most often take the form of a pithy story recounting an incident or verbal exchange between a master and student, or between two masters. These anecdotes were gathered into teaching collections in medieval China; standard collections worked on by Zen students today include the Mumonkan, the Hekiganroku and the Shōyōroku. Students who have been assigned a kōan in dokusan have the task of demonstrating to the teacher their grasp of the essential meaning of the incident or exchange.

Kyōsaku

 

The stick, or encouragement stick. The use of the stick during formal rounds of meditation is said to date to ancient China where it was introduced as a way to rouse sitters who had nodded off while sitting. Today it is used more generally to rouse energy and determination, and to cut off the wanderings or daydreams of the mind. Sitters are struck twice on each shoulder on the trapezius muscle, the spot known in Chinese medicine as the ‘triple warmer’ acupuncture meridian. Receiving the stick is always optional; it is never used as a form of punishment.

 

Linji

 

Linji Yixuan (d. 866), or Rinzai Gigen in Japanese, was one of the most renowned Chinese Zen masters of the Tang Dynasty period (often known as ‘the Golden Age of Zen’) and the founder of the Linji teaching lineage, which became the Rinzai school in Japan (see under ‘Sōtō and Rinzai’). Linji was known for his fierce style of teaching which included many shouts and blows. His sayings and teachings are recorded in the Linji-lu or Record of Linji.

 

Madhyamaka

 

The ‘Middle Way’ philosophy of the Mahāyāna branch of Buddhism has its origins in the work of Nāgārjuna. Madhyamaka teaches that no single philosophical position can be constructed and defended as ultimate by logical means; rather arguments pro and con may always be marshalled. In particular neither a nihilistic nor an absolutist view of reality can be ultimately defended.

Mahāyāna

 

See under Theravāda, Mahayānā, Vajrayāna.

 

Manjuśrī

 

The Bodhisattva of Wisdom. See Bodhisattva.

 

Mara

 

The Buddhist tempter; a personification of evil and death. Mara appeared to the Buddha, as he does to us, as the inner voice questioning our own worthiness or ability to persevere on the spiritual journey.

Mu (Chinese: Wu)

 

Literally ‘no’ or ‘not’, ‘Mu’ is the famous reply of Zen Master Jōshū (Zhaozhou) in the first case of the Mumonkan: A monk asked Joshu, ‘Has the dog Buddha nature or not?’ Joshu said, ‘Mu.’ Through the centuries this koan has gained fame as the one most commonly assigned as a first koan to Zen students taking up koan work. Students are advised not to contemplate the exchange as a whole, but rather, as Master Mumon instructs in his commentary to the case, to ‘cut off the mind road’ and ‘make your whole body a mass of doubt, and with your three hundred and sixty bones and joints and your eighty-four thousand hair follicles concentrate on this one word, Mu. Day and night, keep digging into it’.

 

Mumonkan, Mumon

 

The Mumonkan, called in English the The Gateless Barrier or The Gateless Gate is one of the collections of koans that are part of the Zen koan curriculum, and in the Mumonkan each koan is accompanied by a commentary and a verse written by Master Mumon (1183–1260, Wumen in Chinese), who assembled the collection.

 

Nāgārjuna (c. 150 – c. 250 C.E.)

 

Foundational philosopher of the Mahāyāna. Madhyamaka (Middle Way) philosophy and the Prajñāpāramitā (Perfection of Wisdom) sūtras are based in his teaching. See also under Emptiness.

Nirvāna (Nibbana in Pali)

 

Literally ‘extinction’ or ‘snuffing out’ as of a candle, nirvana is the extinction of a separate sense of self and the complete liberation from Samsāra or the Wheel of Birth and Death. This may be viewed as a state of non-returning to a human or other form, or (in the Mahāyāna teachings) as a state of liberation within the world of Samsāra, where all dualistic notions (pain and pleasure, gain and loss) have been transcended. See also Three Dharma Seals.

 

Pali and Sanskrit

 

The classical languages of the Buddhist scriptures. The words of the Buddha were transmitted orally for approximately the first five hundred years after his Parinirvāna, but were eventually recorded in the Pali language in the first century C.E. These texts of the ‘Pali canon’ form the basis of Theravāda teaching and are accepted by Mahāyāna practitioners as well. At close to the same time that the Pali canon was coming into being, other writings also appeared which reflected the teachings of the then-developing Mahāyāna school. These writings were mostly in Sanskrit, the most ancient classical language of India. Pali is closely related to Sanskrit, but is somewhat more simplified and modernised. See also Sūtta, Sūtra.

 

Pāramitā

 

The pāramitās, most commonly listed as six in number, are the ‘perfections’, or qualities to be perfected by a bodhisattva on the path to realisation. They are sometimes called the bodhisattva trainings.

Parinirvāna

 

The nirvāna that occurs upon the death of someone who has achieved liberation. Such a person is known as a non-returner in the Pali texts.

 

Prajnā

 

See under The Threefold Training

 

Pratītyasamutpāda (Dependent Co-arising or Interbeing)

 

The Twelve Links of Dependent Co-arising is a subtle and complex teaching exploring the origins of our world, our lives and our consciousness, and the ways in which they actually co-arise. Depending which Sūtta is studied, there may be a different number of links given, but the most popular presentation is of Twelve Links as follows: ignorance, karmic formations, consciousness, name-and-form, sixfold sense bases, contact, feeling, craving, attachment, becoming, birth, suffering. The links are very often depicted, each with a traditional illustration, in the form of a wheel (the Wheel of Life). The circular presentation helps to emphasise that the links do not (or do not solely) appear in temporal fashion, one after the other, but that they co-arise. At the centre of the wheel are three animals representing the Three Poisons which drive the whole system; the Three Poisons are encircled by the Six Realms of Unenlightened Existence, and these are encircled in turn by the Twelve Links. The whole wheel is held in the clutches of Yama Raja, the Lord of Death.

Precepts

 

May refer to the Ten Cardinal Precepts, or more broadly to the Ten Cardinal Precepts plus the Three Refuges and the Three General Resolutions. These precepts are descriptions of the ethical behaviour that is the foundation of Buddhist practice.

 

Rakusu

 

A traditional Japanese garment that represents the Buddha’s robe in abbreviated form. The sewing and wearing of a rakusu represents a commitment to the Buddhist Path and to a particular teaching lineage, and there are different styles and colours of rakusu for lay practitioners, for priests, and for teachers.

 

Rinzai

 

For the Rinzai school, see ‘Sōtō and Rinzai’. For Zen Master Rinzai, see under Linji.

Rōshi

 

‘Rōshi’ is an honorific term translating roughly as ‘old teacher’. In English, the term is often placed before the person’s name (Rōshi Kapleau, Rōshi Kjolhede), but the traditional Japanese format is to attach the term to the end of the name (Yasutani-rōshi, Harada-rōshi).

 

Samadhi

 

See under The Threefold Training.

 

Samsāra

 

The world of unenlightened existence, of cause and effect and karma. This is the world depicted by the Wheel of Life (see under Pratītyasamutpāda) and marked by suffering, impermanence and instability. See also under Nirvāna.

Samu

 

Work practice.

 

Sangha

 

The community of Buddhist practitioners. At various times and places ‘sangha’ has had somewhat varying connotations. Historically in the Theravāda it has often been used to refer to the ordained monastic Sangha only, with lay people seen as supporters of the Sangha. However there are also early references to the Arya Sangha, meaning just those practitioners (whether ordained or lay) who have attained enlightenment, as well as references to the Fourfold Sangha of male monastics, female monastics, laymen and laywomen. In the Mahāyāna, and particularly in the West, the term is most frequently used for any Buddhist community that practices together as well as for the community of all Buddhist practitioners worldwide. Even more expansively, all those who are working to uncover truth and to live in accordance with ethical principles may be seen as Sangha, whether or not they subscribe to specifically Buddhist teachings. See also under Three Jewels.

 

Śāntideva (Shantideva)

 

Great eighth-century Indian teacher and author of The Way of the Bodhisattva, a work which continues to inspire practitioners with its call to compassion and bodhicitta. Among many famous verses from this work is one which is said to be a favourite prayer of the Dalai Lama:

For as long as space remains,

For as long as sentient beings remain,

Until then may I too remain

To dispel the miseries of the world.

Sensei

 

The title ‘Sensei’ simply means ‘teacher’, or ‘one who walks ahead’ in Japanese. In Zen it is used by those authorised to teach as a Dharma Heir in a particular lineage. As with the title ‘Rōshi’ it can be placed before the teacher’s name in English (Sensei Wrightson), but the traditional Japanese format is to attach the term to the end of the given name (Amala-sensei).

 

Śīla

 

See under The Threefold Training.

 

Six Realms of Unenlightened Existence

 

There are traditionally six realms into which those still bound to the Wheel of Birth and Death may be born: the Hell Realms, the Hungry Ghost Realm, the Animal Realm, the realm of the Asuras or jealous gods, the Human Realm and the realm of the Devas or happy gods. Birth in the human realm is considered precious because it can provide optimal circumstances for attaining enlightenment: sufficient suffering or dissatisfaction to spur us to practice, combined, ideally, with sufficient leisure and opportunity to pursue it. While birth in the blissful Deva realms may seem preferable, the Devas remain attached to their pleasures and comforts which will, however, eventually fade, even if only after many eons. Today the Six Realms are often interpreted from a psychological perspective as representing different mind states to which we are all subject, or as states which human beings are capable of creating for themselves here on earth through violence, addictions and so forth. See also under Pratītyasamutpāda.

Sōtō and Rinzai

 

The two major schools of Zen in Japan. The Sōtō school is descended from the Chinese Caodong school founded by Dongshan Liangjie the ninth century. Master Dōgen travelled to China in the thirteenth century and brought the teachings of this school back to Japan. Today the sect is associated especially with the practice of shikantaza or ‘just sitting’, a practice taught in China as ‘silent illumination’ by the twelfth-century master Hongzhi as well as by Dōgen’s own teacher, Master Rujing. The Rinzai school is descended from the Chinese Linji school, founded by ninth-century master Linji Yixuan. Historically associated with a fierce and dynamic teaching style, the school today emphasises the investigation of koans. Several other Chinese schools of Chan either died out or did not take root in Japan. In twentieth-century Japan, Daiun Sogaku Harada, a priest of the Sōtō school, came to feel that the Sōtō sect placed an insufficient emphasis on the possibility of awakening to our True Nature, and to this effect he pursued koan work with a Rinzai teacher. Harada-rōshi’s Dharma heir Yasutani, was likewise ordained originally as a Sōtō priest, but, after working with Harada-rōshi, founded a new lineage, the Sambō Kyodan, or Three Treasures Order. This teaching lineage seeks to hand on the best of both the Sōtō and Rinzai traditions in an amalgam sometimes known as ‘Integral Zen’. The Harada-Yasutani lineage has been powerfully influential in Western Zen. (For a complete list of Dharma heirs in this lineage see here.) Rōshi Kapleau studied in Japan with both Harada-rōshi and Yasutani-rōshi (his main teacher).

 

Śūnyatā (Shunyata)

 

See under Emptiness.

 

Sūtra, Sūtta

 

‘Sūtra’ is the Sanskrit form and ‘sūtta’ the Pali form of the word that refers to texts containing the words of the Buddha.

Teisho

 

A Dharma talk delivered by a Zen teacher during a formal block of sitting.

 

Theravāda, Mahāyāna, Vajrayāna

 

Buddhism as practiced today in different parts of the world can be divided into three main branches: Theravāda (‘the way of the elders’), Mahāyāna (‘the great vehicle’) and Vajrayāna (‘the diamond/ thunderbolt vehicle’). The first is most commonly practiced in Southeast Asia, the second in East Asia, and the third in Tibet and adjacent regions. As its name implies, Theravādan Buddhism is the most historically conservative. Its teaching and practices hew closely to the Pali canon. The traditions of the Mahāyāna developed in ancient India alongside those of the Theravāda, but emphasised a perhaps more popular stream of teachings, focused on the veneration of great Bodhisattvas, the liberation of all beings and the conviction that all are inherently Buddhas. Vajrayāna is the youngest tradition of the three. Its teachings were brought from India at a time when Tantric or esoteric practices were dominant there, and these form the hallmark of the Vajrayāna. Some scholars classify the Vajrayāna as a branch of Mahāyāna Buddhism, while others see it as a separate branch altogether. All Buddhist practitioners accept as valid the teachings of the Pali canon; practitioners of the Mahāyāna and Vajrayāna adhere as well to the teachings of the Mahāyāna Sūtras, while Vajrayāna practitioners add in also their own later texts and traditions. See also under Pali and Sanskrit.

 

Three Dharma Seals

 

Impermanence (aniccā), No-self (anattā), and Suffering (dukkha). Any system of teaching or instruction which does not acknowledge these three characteristics of existence is said to be a non-Buddhist teaching. However, teachers of the Mahāyāna sometimes replace dukkha, suffering, with nirvāna or the end of suffering. See also under dukkha and nirvāna.

Three Jewels

 

To take refuge in the Three Jewels, or Treasures, is the means of formally setting out on the Buddhist path (see under Jukai above), and many Buddhists recite the Three Refuges on a daily basis. The order of teachers, priests, and lay memebrs established at the Rochester Zen Center by Rōshi Kjolhede is known as the Three Jewels Order. Amala-sensei and those ordained by her are members of this order.

 

Three Poisons

 

Greed, hatred and delusion are known as the Three Poisons. Just as the precepts are descriptive of enlightened action, so the Three Poisons are descriptive of the unenlightened mind. We believe that we are separate from ‘things out there’ (our basic delusion), and so we react to things either by liking or disliking, by grasping or pushing away, by saying ‘I want this’ (greed) or ‘I don’t want that’ (hatred or aversion). But as we learn to recognise these poisons in our own minds, we need to see also how they lie at the base of our social ills: wars, exploitation, and environmental degradation; and we need to acknowledge not only the inner work but the outer work that still remains to be done.

 

Threefold Training

 

Śīla (pronounced ‘Sheela’, ethical behaviour), Samādhi (development of meditative concentration) and Prajñā (wisdom). Progress along the Buddhist path is taught as equally dependent on each of these three elements. The last, Wisdom, can refer both to the study of Buddhist scripture and teachings as well as to the transcendental wisdom of enlightenment.

Two Truths

 

Buddhist teaching speaks of ‘relative truth’ and ‘absolute truth’. Relative truth is concerned with the world of karma, of cause and effect, of scientific truth. Absolute truth sees into the ultimate emptiness of the relative world and reveals a perspective of oneness. Awakening reveals that these two aspects of reality are in fact inseparable.

 

Vajrayāna

 

See under Theravāda, Mahāyāna, Vajrayāna.

 

Vipassanā

 

Insight or seeing things as they are. ‘Vipassana’ is also the name of a widespread school of modern (mostly Western) Theravāda Buddhism which teaches Insight Meditation.

Yasutani, Hakuun Ryōkō (1885–1973)

 

See under Sōtō and Rinzai.

 

Zabuton

 

Square meditation mat.

 

Zafu

 

Round meditation cushion.

Zendo

 

Meditation hall.
