A term meaning defilement, impurity, and pollution, broadly referring to cognitive and emotional factors that disturb and obscure the mind. As the self-perpetuating process of affliction in the minds of beings, it is a synonym for saṃsāra. It is often paired with its opposite, vyavadāna, meaning “purification.”

A major śrāvaka disciple and personal attendant of the Buddha Śākyamuni during the last twenty-five years of his life. He was a cousin of the Buddha (according to the Mahāvastu, he was a son of Śuklodana, one of the brothers of King Śuddhodana, which means he was a brother of Devadatta; other sources say he was a son of Amṛtodana, another brother of King Śuddhodana, which means he would have been a brother of Aniruddha).Ānanda, having always been in the Buddha’s presence, is said to have memorized all the teachings he heard and is celebrated for having recited all the Buddha’s teachings by memory at the first council of the Buddhist saṅgha, thus preserving the teachings after the Buddha’s parinirvāṇa. The phrase “Thus did I hear at one time,” found at the beginning of the sūtras, usually stands for his recitation of the teachings. He became a patriarch after the passing of Mahākāśyapa.

Yeshé Dé (late eighth to early ninth century) was the most prolific translator of sūtras into Tibetan. Altogether he is credited with the translation of more than one hundred sixty sūtra translations and more than one hundred additional translations, mostly on tantric topics. In spite of Yeshé Dé’s great importance for the propagation of Buddhism in Tibet during the imperial era, only a few biographical details about this figure are known. Later sources describe him as a student of the Indian teacher Padmasambhava, and he is also credited with teaching both sūtra and tantra widely to students of his own. He was also known as Nanam Yeshé Dé, from the Nanam (sna nam) clan.

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 Indian preceptor and one of the translators of this sūtra.

A word that is used to refer to something else, a name, or a term.

In the context of Buddhist philosophy, one way to describe experience in terms of eighteen elements (eye, form, and eye consciousness; ear, sound, and ear consciousness; nose, smell, and nose consciousness; tongue, taste, and tongue consciousness; body, touch, and body consciousness; and mind, mental phenomena, and mind consciousness).This also refers to the elements of the world, which can be enumerated as four, five, or six. The four elements are earth, water, fire, and air. A fifth, space, is often added, and the sixth is consciousness.

The laywoman who features prominently in this sūtra, as well as the name of one thousand laywoman of the past who attained nirvāṇa, according to the Buddha in this sūtra.

Brahman is a Sanskrit term referring to what is highest (parama) and most important (pradhāna); the Nibandhana commentary explains brahman as meaning here nirvāṇa, and thus the brahman conduct is the “conduct toward brahman,” the conduct that leads to the highest liberation, i.e., nirvāṇa. This is explained as “the path without outflows,” which is the “truth of the path” among the four truths of the noble ones. Other explanations (found in the Pāli tradition) take “brahman conduct” to mean the “best conduct,” and also the “conduct of the best,” i.e., the buddhas. In some contexts, “brahman conduct” refers more specifically to celibacy, but the specific referents of this expression are many.

One who is still under the influence of the “intoxicants” (āsrava), of which there are sometimes said to be four: “lust” (kāma), “becoming” (bhava), “ignorance” (avidyā), and “views” (dṛṣṭi)

A noun derived from the verb mā, (“to create”) and connected to the term māyā (“magical illusion”).

A noun derived from the verb mā (“to create”) and connected to the term māyā (“magical illusion”).

The term bhikṣu, often translated as “monk,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term literally means “beggar” or “mendicant,” referring to the fact that Buddhist monks and nuns‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity. In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a monk follows 253 rules as part of his moral discipline. A nun (bhikṣuṇī; dge slong ma) follows 364 rules. A novice monk (śrāmaṇera; dge tshul) or nun (śrāmaṇerikā; dge tshul ma) follows thirty-six rules of moral discipline (although in other vinaya traditions novices typically follow only ten).

The term bhikṣuṇī, often translated as “nun,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term bhikṣu (to which the female grammatical ending ṇī is added) literally means “beggar” or “mendicant,” referring to the fact that Buddhist nuns and monks‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity. In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a bhikṣuṇī follows 364 rules and a bhikṣu follows 253 rules as part of their moral discipline.For the first few years of the Buddha’s teachings in India, there was no ordination for women. It started at the persistent request and display of determination of Mahāprajāpatī, the Buddha’s stepmother and aunt, together with five hundred former wives of men of Kapilavastu, who had themselves become monks. Mahāprajāpatī is thus considered to be the founder of the nun’s order.

The Tibetan can translate both a noun (ālambana) and a related verb (in which case the third person singular is ālambate, “[one] perceives or conceives [something] as having an objective basis”). This term is tied to the general idea that an act of sense perception or mental conception takes an object of some kind that forms the basis or support for its continuing perception or conception.

This refers to what occurs at the end of an arhat’s or a buddha’s life. When nirvāṇa is attained at awakening, whether as an arhat or buddha, all suffering, afflicted mental states (kleśa), and causal processes (karman) that lead to rebirth and suffering in cyclic existence have ceased, but due to previously accumulated karma, the aggregates of that life remain and must still exhaust themselves. It is only at the end of life that these cease, and since no new aggregates arise, the arhat or buddha is said to attain parinirvāṇa, meaning “complete” or “final” nirvāṇa. This is synonymous with the attainment of nirvāṇa without remainder (anupadhiśeṣanirvāṇa). According to the Mahāyāna view of a single vehicle (ekayāna), the arhat’s parinirvāṇa at death, despite being so called, is not final. The arhat must still enter the bodhisattva path and reach buddhahood (see Unraveling the Intent, Toh 106, 7.14.) On the other hand, the parinirvāṇa of a buddha, ultimately speaking, should be understood as a display manifested for the benefit of beings; see The Teaching on the Extraordinary Transformation That Is the Miracle of Attaining the Buddha’s Powers (Toh 186), 1.32. The term parinirvāṇa is also associated specifically with the passing away of the Buddha Śākyamuni, in Kuśinagara, in northern India.

One of the first Buddhist monasteries, located in a park outside Śrāvastī, the capital of the ancient kingdom of Kośala in northern India. This park was originally owned by Prince Jeta, hence the name Jetavana, meaning Jeta’s grove. The wealthy merchant Anāthapiṇḍada, wishing to offer it to the Buddha, sought to buy it from him, but the prince, not wishing to sell, said he would only do so if Anāthapiṇḍada covered the entire property with gold coins. Anāthapiṇḍada agreed, and managed to cover all of the park except the entrance, hence the name Anāthapiṇḍadasyārāmaḥ, meaning Anāthapiṇḍada’s park. The place is usually referred to in the sūtras as “Jetavana, Anāthapiṇḍada’s park,” and according to the Saṃghabhedavastu the Buddha used Prince Jeta’s name in first place because that was Prince Jeta’s own unspoken wish while Anāthapiṇḍada was offering the park. Inspired by the occasion and the Buddha’s use of his name, Prince Jeta then offered the rest of the property and had an entrance gate built. The Buddha specifically instructed those who recite the sūtras to use Prince Jeta’s name in first place to commemorate the mutual effort of both benefactors. Anāthapiṇḍada built residences for the monks, to house them during the monsoon season, thus creating the first Buddhist monastery. It was one of the Buddha’s main residences, where he spent around nineteen rainy season retreats, and it was therefore the setting for many of the Buddha’s discourses and events. According to the travel accounts of Chinese monks, it was still in use as a Buddhist monastery in the early fifth century ᴄᴇ, but by the sixth century it had been reduced to ruins.

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.

During the life of the Buddha, Śrāvastī was the capital city of the powerful kingdom of Kośala, ruled by King Prasenajit, who became a follower and patron of the Buddha. It was also the hometown of Anāthapiṇḍada, the wealthy patron who first invited the Buddha there, and then offered him a park known as Jetavana, Prince Jeta’s Grove, which became one of the first Buddhist monasteries. The Buddha is said to have spent about twenty-five rainy seasons with his disciples in Śrāvastī, thus it is named as the setting of numerous events and teachings. It is located in present-day Uttar Pradesh in northern India.

Seemingly conceived of as either the state or nature of being or that of a being. One of a number of applications of the term dhātu, which can have the sense of an element or constituent part of the world and of the person. It can also be used in the sense of “the true state of things” (dharmadhātu) and “the sphere of the worlds” (lokadhātu).

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 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.

An epithet for the Buddha.

One who is no longer under the influence of the “intoxicants” (āsrava), of which there are sometimes said to be four: “lust” (kāma), “becoming” (bhava), “ignorance” (avidyā), and “views” (dṛṣṭi)
