Shantideva (Sanskrit: Śāntideva; ; ; ; ) 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. Biography The Zhansi Lun of the East Asian Mādhyamaka identifies two different individuals given the name "Shant inideva": their founder of the Avaivartika Sangha in the 6th century CE and a later Shantideva who studied at Nalanda in the 8th century CE and appears to be the source of the Tibetan biographies. Archaeological discoveries support this thesis. Two Tibetan sources of the life of Shantideva are the historians Buton Rinchen Drub and Tāranātha. Recent scholarship has brought to light a short Sanskrit life of Shantideva in a 14th-century CE Nepalese manuscript. An accessible account that follows the Butön closely can be found in Kunzang Pelden, The Nectar of Manjushri's speech. Shantideva was born in the Saurastra (in modern Gujarat), son of King Kalyanavarman, and he went by the name Śantivarman. According to Pema Chödrön, "Shantideva was not well liked at Nalanda." After being goaded into giving a talk to the entire university body, Shantideva delivered The Way of the Bodhisattva. Works Śikṣāsamuccaya The Śikṣāsamuccaya ("Training Anthology") is a prose work in nineteen chapters. It is organized as a commentary on twenty-seven short mnemonic verses known as the Śikṣāsamuccaya Kārikā. It consists primarily of quotations (of varying length) from sūtras, authoritative texts considered to be the word of the Buddha — generally those sūtras associated with Mahāyāna tradition, including the Samadhiraja Sutra. Bodhicaryavatara Shantideva is particularly renowned as the author of the Bodhisattvacaryāvatāra. A variety of English translations exist, sometimes glossed as "A Guide to the Bodhisattva's Way of Life" or "Entering the Path of Enlightenment." It is a long poem describing the process of enlightenment from the first thought to full buddhahood and is still studied by Mahayana and Vajrayana Buddhists today. An introduction to and commentary on the Bodhisattvacaryāvatāra by the 14th Dalai Lama called A Flash of Lightning in the Dark of Night was printed in 1994. A commentary on the Patience chapter was provided by the Dalai Lama in Healing Anger (1997), and his commentaries on the Wisdom chapter can be found in Practicing Wisdom (2004). Kunzang Palden has written a commentary based on that given by Patrul
