According to Buddhist tradition, one who is worthy of worship (pūjām arhati), or one who has conquered the enemies, the mental afflictions (kleśa-ari-hata-vat), and reached liberation from the cycle of rebirth and suffering. It is the fourth and highest of the four fruits attainable by śrāvakas. Also used as an epithet of the Buddha.

An epithet for a buddha. The Sanskrit means “one who has good fortune.” In Sanskrit literature the term is used for the most eminent of humans or the divine, but in a Buddhist context it refers explicitly to a buddha. The Tibetan translation of the term bcom ldan ’das is not a literal translation of the Sanskrit but means bcom: “one who has conquered (the māras or afflictions)”; ldan: “possesses (the qualities of enlightenment)”; and ’das: “has transcended (saṃsāra, or both saṃsāra and nirvāṇa).”

The Gaṅgā, or Ganges in English, is considered to be the most sacred river of India, particularly within the Hindu tradition. It starts in the Himalayas, flows through the northern plains of India, bathing the holy city of Vārāṇasī, and meets the sea at the Bay of Bengal, in Bangladesh. In the sūtras, however, this river is mostly mentioned not for its sacredness but for its abundant sands‍—noticeable still today on its many sandy banks and at its delta‍—which serve as a common metaphor for infinitely large numbers.

According to Buddhist cosmology, as explained in the Abhidharmakośa, it is one of the four rivers that flow from Lake Anavatapta and cross the southern continent of Jambudvīpa‍—the known human world or more specifically the Indian subcontinent.

A number calculated by multiplying a koṭi (bye ba), or ten million, by a niyuta (khrag khrig), or a hundred billion according to the Abhidharma system (although it is only one million in Classical Sanskrit), and by a śatasahasra (brgya stong), or one hundred thousand, all of which together equals ten to the 23rd power or a hundred sextillion. This term is often used as to express a number so large as to be inconceivable.

Literally, the “ripening.”

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.”

The ancient capital of Magadha prior to its relocation to Pāṭaliputra during the Mauryan dynasty, Rājagṛha is one of the most important locations in Buddhist history. The literature tells us that the Buddha and his saṅgha spent a considerable amount of time in residence in and around Rājagṛha‍—in nearby places, such as the Vulture Peak Mountain (Gṛdhrakūṭaparvata), a major site of the Mahāyāna sūtras, and the Bamboo Grove (Veṇuvana)‍—enjoying the patronage of King Bimbisāra and then of his son King Ajātaśatru. Rājagṛha is also remembered as the location where the first Buddhist monastic council was held after the Buddha Śākyamuni passed into parinirvāṇa. Now known as Rajgir and located in the modern Indian state of Bihar.

The set of seven precious materials or substances includes a range of precious metals and gems, but their exact list varies. The set often consists of gold, silver, beryl, crystal, red pearls, emeralds, and white coral, but may also contain lapis lazuli, ruby, sapphire, chrysoberyl, diamonds, etc. The term is frequently used in the sūtras to exemplify preciousness, wealth, and beauty, and can describe treasures, offering materials, or the features of architectural structures such as stūpas, palaces, thrones, etc. The set is also used to describe the beauty and prosperity of buddha realms and the realms of the gods.

In other contexts, the term saptaratna can also refer to the seven precious possessions of a cakravartin or to a set of seven precious moral qualities.

One of the standard epithets of the buddhas. A recurrent explanation offers three different meanings for su- that are meant to show the special qualities of “accomplishment of one’s own purpose” (svārthasampad) for a complete buddha. Thus, the Sugata is “well” gone, as in the expression su-rūpa (“having a good form”); he is gone “in a way that he shall not come back,” as in the expression su-naṣṭa-jvara (“a fever that has utterly gone”); and he has gone “without any remainder” as in the expression su-pūrṇa-ghaṭa (“a pot that is completely full”). According to Buddhaghoṣa, the term means that the way the Buddha went (Skt. gata) is good (Skt. su) and where he went (Skt. gata) is good (Skt. su).

An epithet for a buddha. The Sanskrit compound may be ambiguously parsed to mean either “thus-gone one” (tathā + gata) or “thus-come one” (tathā + āgata); this concurs with the Tibetan translation with the verb gshegs, which can mean either “to come” or “to go.” The Sanskrit root √gam (“to go”) also often denotes the meaning “to understand,” while tathā refers to thusness, suchness, or the way things really are, so the tathāgata can be rendered as the one who understands things as they really are or who has gone to such a state.

A term from Abhidharma cosmology referring to one thousand dichiliocosms, or one billion world systems.

The Gṛdhra­kūṭa, literally Vulture Peak, was a hill located in the kingdom of Magadha, in the vicinity of the ancient city of Rājagṛha (modern-day Rajgir, in the state of Bihar, India), where the Buddha bestowed many sūtras, especially the Great Vehicle teachings, such as the Prajñāpāramitā sūtras. It continues to be a sacred pilgrimage site for Buddhists to this day.
