“Unconquered.” An alternate name for the bodhisattva Maitreya.

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.

The term can be understood to mean “great courageous one” or "great hero,” or (from the Sanskrit) simply “great being,” and is almost always found as an epithet of “bodhisattva.” The qualification “great” in this term, according to the majority of canonical definitions, focuses on the generic greatness common to all bodhisattvas, i.e., the greatness implicit in the bodhisattva vow itself in terms of outlook, aspiration, number of beings to be benefited, potential or eventual accomplishments, and so forth. In this sense the mahā- is closer in its connotations to the mahā- in “Mahāyāna” than to the mahā- in “mahāsiddha.” While individual bodhisattvas described as mahāsattva may in many cases also be “great” in terms of their level of realization, this is largely coincidental, and in the canonical texts the epithet is not restricted to bodhisattvas at any particular point in their career. Indeed, in a few cases even bodhisattvas whose path has taken a wrong direction are still described as bodhisattva mahāsattva.

Later commentarial writings do nevertheless define the term‍—variably‍—in terms of bodhisattvas having attained a particular level (bhūmi) or realization. The most common qualifying criteria mentioned are attaining the path of seeing, attaining irreversibility (according to its various definitions), or attaining the seventh bhūmi.

This term, although commonly translated as “appropriation,” also means “grasping” or “clinging,” but it has a particular meaning as the ninth of the twelve links of dependent origination, situated between craving (tṛṣṇā, sred pa) and becoming or existence (bhava, srid pa). In some texts, four types of appropriation (upādāna) are listed: that of desire (rāga), view (dṛṣṭi), rules and observances as paramount (śīla­vrata­parāmarśa), and belief in a self (ātmavāda).

The largest universe described in Buddhist cosmology. This term, in Abhidharma cosmology, refers to 1,000^³ world systems, i.e., 1,000 “dichiliocosms” or “two thousand great thousand world realms” (dvi­sāhasra­mahā­sāhasra­lokadhātu), which are in turn made up of 1,000 first-order world systems, each with its own Mount Sumeru, continents, sun and moon, etc.

The Sanskrit term śrāvaka, and the Tibetan nyan thos, both derived from the verb “to hear,” are usually defined as “those who hear the teaching from the Buddha and make it heard to others.” Primarily this refers to those disciples of the Buddha who aspire to attain the state of an arhat seeking their own liberation and nirvāṇa. They are the practitioners of the first turning of the wheel of the Dharma on the four noble truths, who realize the suffering inherent in saṃsāra and focus on understanding that there is no independent self. By conquering afflicted mental states (kleśa), they liberate themselves, attaining first the stage of stream enterers at the path of seeing, followed by the stage of once-returners who will be reborn only one more time, and then the stage of non-returners who will no longer be reborn into the desire realm. The final goal is to become an arhat. These four stages are also known as the “four results of spiritual practice.”

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.

A general term applied to spiritual practitioners who live as ascetic mendicants. In Buddhist texts, the term usually refers to Buddhist monastics, but it can also designate a practitioner from other ascetic/monastic spiritual traditions. In this context śramaṇa is often contrasted with the term brāhmaṇa (bram ze), which refers broadly to followers of the Vedic tradition. Any renunciate, not just a Buddhist, could be referred to as a śramaṇa if they were not within the Vedic fold. The epithet Great Śramaṇa is often applied to the Buddha.

In Sanskrit, the term nirvāṇa literally means “extinguishment” and the Tibetan mya ngan las ’das pa literally means “gone beyond sorrow.” As a general term, it refers to the cessation of all suffering, afflicted mental states (kleśa), and causal processes (karman) that lead to rebirth and suffering in cyclic existence, as well as to the state in which all such rebirth and suffering has permanently ceased.

More specifically, three main types of nirvāṇa are identified. (1) The first type of nirvāṇa, called nirvāṇa with remainder (sopadhiśeṣanirvāṇa), is the state in which arhats or buddhas have attained awakening but are still dependent on the conditioned aggregates until their lifespan is exhausted. (2) At the end of life, given that there are no more causes for rebirth, these aggregates cease and no new aggregates arise. What occurs then is called nirvāṇa without remainder ( anupadhiśeṣanirvāṇa), which refers to the unconditioned element (dhātu) of nirvāṇa in which there is no remainder of the aggregates. (3) The Mahāyāna teachings distinguish the final nirvāṇa of buddhas from that of arhats, the nirvāṇa of arhats not being considered ultimate. The buddhas attain what is called nonabiding nirvāṇa (apratiṣṭhitanirvāṇa), which transcends the extremes of saṃsāra and nirvāṇa, i.e., existence and peace. This is the nirvāṇa that is the goal of the Mahāyāna path.

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.

Also known as Benares, one of the oldest cities of northeast India on the banks of the Ganges, in modern-day Uttar Pradesh. It was once the capital of the ancient kingdom of Kāśi, and in the Buddha’s time it had been absorbed into the kingdom of Kośala. It was an important religious center, as well as a major city, even during the time of the Buddha. The name may derive from being where the Varuna and Assi rivers flow into the Ganges. It was on the outskirts of Vārāṇasī that the Buddha first taught the Dharma, in the location known as Deer Park (Mṛgadāva). For numerous episodes set in Vārāṇasī, including its kings, see The Hundred Deeds, Toh 340.
