CatuṣkoṭiCatuṣkoṭi (Sanskrit; Devanagari: चतुष्कोटि, , Sinhalese:චතුස්කෝටිකය) refers to logical argument(s) of a 'suite of four discrete functions' or 'an indivisible quaternity' that has multiple applications and has been important in the Indian logic and the Buddhist logico-epistemological traditions, particularly those of the Madhyamaka school. In particular, the catuṣkoṭi is a "four-cornered" system of argumentation that involves the systematic examination of each of the 4 possibilities of a proposition, P: P; that is being.
History of Buddhism in IndiaBuddhism is an ancient Indian religion, which arose in and around the ancient Kingdom of Magadha (now in Bihar, India), and is based on the teachings of Gautama Buddha who was deemed a "Buddha" ("Awakened One"), although Buddhist doctrine holds that there were other Buddhas before him. Buddhism spread outside of Magadha starting in the Buddha's lifetime. During the reign of the Mauryan Emperor Ashoka The Great, the Buddhist community split into two branches: the Mahāsāṃghika and the Sthaviravāda, each of which spread throughout India and split into numerous sub-sects.
JñānaIn Indian philosophy and religions, (, ˈdʑɲaːnɐ) is "knowledge". The idea of jñāna centers on a cognitive event which is recognized when experienced. It is knowledge inseparable from the total experience of reality, especially the total or divine reality (Brahman). The root ज्ञा- jñā- is cognate to Slavic znati, English know, as well as to the Greek γνώ- (as in γνῶσις gnosis) and Lithuanian žinoti. Its antonym is अज्ञान ajñāna "ignorance".
Je TsongkhapaTsongkhapa (tsoŋˈkhapa, meaning: "the man from Tsongkha" or "the Man from Onion Valley", c. 1357–1419) was an influential Tibetan Buddhist monk, philosopher and tantric yogi, whose activities led to the formation of the Gelug school of Tibetan Buddhism. He is also known by his ordained name Losang Drakpa (, Skt. Sumatikīrti) or simply as "Je Rinpoche" (, "Precious Lord"). He is also known by Chinese as Zongkapa Lobsang Zhaba or just Zōngkàbā (宗喀巴).
ShantidevaShantideva (Sanskrit: Śāntideva; ; ; Шантидэва гэгээн; Tịch Thiên) was an 8th-century CE Indian philosopher, Buddhist monk, poet, and scholar at the mahavihara of Nalanda. He was an adherent of the Mādhyamaka philosophy of Nāgārjuna. He is also considered to be one of the 84 mahasiddhas and is known as Bhusuku. The Zhansi Lun of the East Asian Mādhyamaka identifies two different individuals given the name "Shantideva": the founder of the Avaivartika Mahāyānika Sangha in 6th century CE (in Samataṭa, modern Bangladesh) and a later Shantideva who studied at Nalanda in the 8th century CE and appears to be the source of the Tibetan biographies.
Indra's netIndra's net (also called Indra's jewels or Indra's pearls, Sanskrit Indrajāla, Chinese: 因陀羅網) is a metaphor used to illustrate the concepts of Śūnyatā (emptiness), pratītyasamutpāda (dependent origination), and interpenetration in Buddhist philosophy. The metaphor's earliest known reference is found in the Atharva Veda. It was further developed by the Mahayana school in the 3rd century Buddhāvataṃsaka Sūtra and later by the Huayan school between the 6th and 8th centuries.
MadhyamakālaṃkāraThe Madhyamakālaṃkāra is an 8th-century Buddhist text, believed to have been originally composed in Sanskrit by Śāntarakṣita (725–788), which is extant in Tibetan. The Tibetan text was translated from the Sanskrit by Surendrabodhi () and Jñānasūtra. In the short-verse text of the Madhyamakālaṃkāra, Śāntarakṣita details his philosophical synthesis of the conventional truth of Yogacara with the ultimate truth of the Madhyamaka, assisted by Buddhist logic with a lengthy discussion of the "neither one nor many" argument.
TetralemmaThe tetralemma is a figure that features prominently in the logic of India. It states that with reference to any a logical proposition X, there are four possibilities: (affirmation) (negation) (both) (neither) The history of fourfold negation, the Catuskoti (Sanskrit), is evident in the logico-epistemological tradition of India, given the categorical nomenclature Indian logic in Western discourse.
AnutpadaAnutpāda (अनुत्पाद) is a Buddhist concept for the absence of an origin. In Mahayana Buddhism, "anutpāda" is often symbolized by the letter A. "Anutpāda" means "having no origin", "not coming into existence", "not taking effect", "non-production". "An" also means "not", or "non" "Utpāda" means "genesis", "coming forth", "birth" The Buddhist tradition uses the term "anutpāda" for the absence of an origin or sunyata (voidness). Anutpāda means that dharmas, the constituting elements of reality, do not come into existence.
Rangtong and shentongShentong (Wylie: gzhang stong, "emptiness of other") is term for a type of Buddhist view on emptiness (śūnyatā), Madhyamaka, and the two truths in Indo-Tibetan Buddhism. It is often contrasted with the term rangtong ("self-emptiness"). The term refers to a range of views held by different Tibetan Buddhist figures. The classic shentong view was developed and defended by the Jonang school of Tibetan Buddhism, especially by the great scholar Dölpopa Shérap Gyeltsen (1292–1361).
