An attainment of effortless insight into emptiness and the lack of birth of phenomena. This attainment only occurs on the bodhisattva levels, variously said to occur on the first and eighth bodhisattva levels.

A type of nonhuman being whose precise status is subject to different views, but is included as one of the six classes of beings in the sixfold classification of realms of rebirth. In the Buddhist context, asuras are powerful beings said to be dominated by envy, ambition, and hostility. They are also known in the pre-Buddhist and pre-Vedic mythologies of India and Iran, and feature prominently in Vedic and post-Vedic Brahmanical mythology, as well as in the Buddhist tradition. In these traditions, asuras are often described as being engaged in interminable conflict with the devas (gods).

One of the “eight close sons of the Buddha,” he is also known as the bodhisattva who embodies compassion. In certain tantras, he is also the lord of the three families, where he embodies the compassion of the buddhas. In Tibet, he attained great significance as a special protector of Tibet, and in China, in female form, as Guanyin, the most important bodhisattva in all of East Asia.

A term that includes all the many factors, whether associated with body, speech, or mind, that underlie present or future suffering, including karma and the afflictions, the various kinds of obscuration, and the aggregates themselves.

In Buddhist literature, this is an epithet applied to buddhas, most often to Śākyamuni. The Sanskrit term generally means “possessing fortune,” but in specifically Buddhist contexts it implies that a buddha is in possession of six auspicious qualities (bhaga) associated with complete awakening. The Tibetan term‍—where bcom is said to refer to “subduing” the four māras, ldan to “possessing” the great qualities of buddhahood, and ’das to “going beyond” saṃsāra and nirvāṇa‍—possibly reflects the commentarial tradition where the Sanskrit bhagavat is interpreted, in addition, as “one who destroys the four māras.” This is achieved either by reading bhagavat as bhagnavat (“one who broke”), or by tracing the word bhaga to the root √bhañj (“to break”).

An early term used to denote the Buddha’s teaching. “Dharma” refers to the sūtras and “Vinaya” to the rules of discipline.

In its earliest use it meant that though the corporeal body of the Buddha had perished, his “body of the Dharma” continued. It also referred to the Buddha’s realization of reality, to his qualities as a whole, or to his teachings as embodying him. It later came to be synonymous with enlightenment or buddhahood, a “body” that can only be “seen” by a buddha.

In different sūtras, the term rnyog pa refers to different sets of problems that beset those on the path. A possible referent here is the set of four (“four kinds of stain”) found in Cultivating Trust in the Great Vehicle (Toh 144, 1.2) namely, anger (khong khro), lack of trust (yid mi ches), hatred (sdang ba), and doubt (the tshom).

The constituents of experience. One way of describing experience and the world is in terms of eighteen elements: eye, form, and eye consciousness; ear, sound, and ear consciousness; nose, odor, and nose consciousness; tongue, taste, and tongue consciousness; body, touch, and body consciousness; and mind, mental objects, and mind consciousness.

Emptiness denotes the ultimate nature of reality, the total absence of inherent existence and self-identity with respect to all phenomena. According to this view, all things and events are devoid of any independent, intrinsic reality that constitutes their essence. Nothing can be said to exist independent of the complex network of factors that gives rise to its origination, nor are phenomena independent of the cognitive processes and mental constructs that make up the conventional framework within which their identity and existence are posited. When all levels of conceptualization dissolve and when all forms of dichotomizing tendencies are quelled through deliberate meditative deconstruction of conceptual elaborations, the ultimate nature of reality will finally become manifest. It is the first of the three gateways to liberation.

The laity who make offerings to the ordained saṅgha.

The ceremony of full or higher ordination by which a male or female novice is confirmed as a fully ordained member of the order of monks or nuns (see Buswell and Lopez 2014, s.v. “upasaṃpadā”).

A class of generally benevolent nonhuman beings who inhabit the skies, sometimes said to inhabit fantastic cities in the clouds, and more specifically to dwell on the eastern slopes of Mount Meru, where they are ruled by the Great King Dhṛtarāṣṭra. They are most renowned as celestial musicians who serve the gods. In the Abhidharma, the term is also used to refer to the mental body assumed by sentient beings during the intermediate state between death and rebirth. Gandharvas are said to live on fragrances (gandha) in the desire realm, hence the Tibetan translation dri za, meaning “scent eater.”

The Sanskrit pravrajyā literally means “going forth,” with the sense of leaving the life of a householder and embracing the life of a renunciant. When the term is applied more technically, it refers to the act of becoming a male novice (śrāmaṇera; dge tshul) or female novice (śrāmaṇerikā; dge tshul ma), this being a first stage leading to full ordination.

An epithet for bodhisattvas.

When not a general reference to extraordinary knowledge and power, this often refers to a set of six specific abilities: divine sight, divine hearing, knowing how to manifest miracles, remembering previous lives, knowing the minds of others, and knowing that all defects have been eliminated. Sometimes listed as five, without the sixth.

One of the five or six classes of sentient beings, into which beings are born as the karmic fruition of past miserliness. As the term in Sanskrit means “the departed,” they are analogous to the ancestral spirits of Vedic tradition, the pitṛs, who starve without the offerings of descendants. It is also commonly translated as “hungry ghost” or “starving spirit,” as in the Chinese 餓鬼 e gui.

They are sometimes said to reside in the realm of Yama, but are also frequently described as roaming charnel grounds and other inhospitable or frightening places along with piśācas and other such beings. They are particularly known to suffer from great hunger and thirst and the inability to acquire sustenance. Detailed descriptions of their realm and experience, including a list of the thirty-six classes of pretas, can be found in The Application of Mindfulness of the Sacred Dharma, Toh 287, 2.­1281– 2.1482.

Insight, also often rendered as wisdom, refers to the profound understanding of the emptiness of all phenomena. It is the sixth of the six perfections. It is often paired with skillful means. Together, they are considered the two indispensable aspects of the bodhisattva path.

A stage on the bodhisattva path where the practitioner will never turn back, or be turned back, from progress toward the full awakening of a buddha.

This term has three meanings: (1) the ultimate nature, (2) the experience of the ultimate nature, and (3) the quiescent state of a worthy one (arhat) to be avoided by bodhisattvas.

In this text, an epithet for Avalokiteśvara.

When the Buddhist teachings are classified according to their power to lead beings to an awakened state, a distinction is made between the teachings of the Lesser Vehicle (Hīnayāna), which emphasizes the individual’s own freedom from cyclic existence as the primary motivation and goal, and those of the Great Vehicle (Mahāyāna), which emphasizes altruism and has the liberation of all sentient beings as the principal objective. As the term “Great Vehicle” implies, the path followed by bodhisattvas is analogous to a large carriage that can transport a vast number of people to liberation, as compared to a smaller vehicle for the individual practitioner.

The bodhisattva Maitreya is an important figure in many Buddhist traditions, where he is unanimously regarded as the buddha of the future era. He is said to currently reside in the heaven of Tuṣita, as Śākyamuni’s regent, where he awaits the proper time to take his final rebirth and become the fifth buddha in the Fortunate Eon, reestablishing the Dharma in this world after the teachings of the current buddha have disappeared. Within the Mahāyāna sūtras, Maitreya is elevated to the same status as other central bodhisattvas such as Mañjuśrī and Avalokiteśvara, and his name appears frequently in sūtras, either as the Buddha’s interlocutor or as a teacher of the Dharma. Maitreya literally means “Loving One.” He is also known as Ajita, meaning “Invincible.”

For more information on Maitreya, see, for example, the introduction to Maitreya’s Setting Out (Toh 198).

Māra, literally “death” or “maker of death,” is the name of the deva who tried to prevent the Buddha from achieving awakening, the name given to the class of beings he leads, and also an impersonal term for the destructive forces that keep beings imprisoned in saṃsāra:

(1) As a deva, Māra is said to be the principal deity in the Heaven of Making Use of Others’ Emanations (paranirmitavaśavartin), the highest paradise in the desire realm. He famously attempted to prevent the Buddha’s awakening under the Bodhi tree‍—see The Play in Full (Toh 95), 21.1‍—and later sought many times to thwart the Buddha’s activity. In the sūtras, he often also creates obstacles to the progress of śrāvakas and bodhisattvas. (2) The devas ruled over by Māra are collectively called mārakāyika or mārakāyikadevatā, the “deities of Māra’s family or class.” In general, these māras too do not wish any being to escape from saṃsāra, but can also change their ways and even end up developing faith in the Buddha, as exemplified by Sārthavāha; see The Play in Full (Toh 95), 21.14 and 21.43. (3) The term māra can also be understood as personifying four defects that prevent awakening, called (i) the divine māra (devaputra­māra), which is the distraction of pleasures; (ii) the māra of Death (mṛtyumāra), which is having one’s life interrupted; (iii) the māra of the aggregates (skandhamāra), which is identifying with the five aggregates; and (iv) the māra of the afflictions (kleśamāra), which is being under the sway of the negative emotions of desire, hatred, and ignorance.

In the general Mahāyāna teachings the mind of awakening (bodhicitta) is the intention to attain the complete awakening of a perfect buddha for the sake of all beings. On the level of absolute truth, the mind of awakening is the realization of the awakened state itself.

Mount Potalaka is the abode of Avalokiteśvara, believed to be an island off the coast of India. The locus classicus for Mount Potalaka is the final chapter of the Buddhāvataṃsaka, the Gaṇḍavyūha Sūtra. It has also been identified as Pothigai Malai or Potityil, in the Tirunelveli district of Tamil Nadu. In Tibet and China, Potalaka was believed to be an island. In Tibet it is usually referred to by the shortened form Potala.

Refers to the entirety of phenomena as synonymous with emptiness or the ultimate nature of all things.

A state of involuntary existence conditioned by afflicted mental states and the imprint of past actions, characterized by suffering in a cycle of life, death, and rebirth. On its reversal, the contrasting state of nirvāṇa is attained, free from suffering and the processes of rebirth.

These can be listed as twelve or as six sense sources (sometimes also called sense fields, bases of cognition, or simply āyatanas).

In the context of epistemology, it is one way of describing experience and the world in terms of twelve sense sources, which can be divided into inner and outer sense sources, namely: (1–2) eye and form, (3–4) ear and sound, (5–6) nose and odor, (7–8) tongue and taste, (9–10) body and touch, (11–12) mind and mental phenomena.

In the context of the twelve links of dependent origination, only six sense sources are mentioned, and they are the inner sense sources (identical to the six faculties) of eye, ear, nose, tongue, body, and mind.

The ultimate absence of marks and signs in perceived objects. One of the three gateways to liberation; the other two are emptiness and wishlessness.

The concept of skillful or expedient means is central to the understanding of the Buddha’s enlightened deeds and the many scriptures that are revealed contingent on the needs, interests, and mental dispositions of specific types of individuals. It is, therefore, equated with compassion and the form body of the buddhas, the rūpakāya.

According to the Great Vehicle, training in skillful means collectively denotes the first five of the six perfections when integrated with wisdom, the sixth perfection. It is therefore paired with wisdom (prajñā), forming the two indispensable aspects of the path. It is also the seventh of the ten perfections. (Provisional 84000 definition. New definition forthcoming.)

The real nature, true quality, or condition of things. Throughout Buddhist discourse this term is used in two distinct ways. In one, it designates the relative nature that is either the essential characteristic of a specific phenomenon, such as the heat of fire and the moisture of water, or the defining feature of a specific term or category. The other very important and widespread way it is used is to designate the ultimate nature of all phenomena, which cannot be conveyed in conceptual, dualistic terms and is often synonymous with emptiness or the absence of intrinsic existence.

This term generally indicates indestructibility and stability. In the sūtras, vajra most often refers to the hardest possible physical substance, said to have divine origins. In some scriptures, it is also the name of the all-powerful weapon of Indra, which in turn is crafted from vajra material. In the tantras, the vajra is sometimes a scepter-like ritual implement, but the term can also take on other esoteric meanings.

The ultimate absence of any wish, desire, or aspiration, even those directed towards buddhahood. One of the three gateways to liberation; the other two are emptiness and signlessness.

A person considered worthy of veneration with material offerings. In the context of Tibetan Buddhist history, this is the term often translated as “priest” when paired with the term “patron” (Tib. sbyin bdag/ yon bdag, Skt. dānapati) in the compound phrase “priest-patron relationship.”

An epithet for bodhisattvas.
