Shantideva 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.

Nalanda was a renowned Buddhist mahavihara in ancient and medieval Magadha, eastern India. Nalanda is considered to be among the greatest centers of learning in the ancient world. It was located near the city of Rajagriha and about 90 kilometres (56 mi) southeast of Pataliputra. Operating from 427 until 1197 CE, Nalanda played a vital role in promoting the patronage of arts and academics during the 5th and 6th century CE, a period that has since been described as the "Golden Age of India" by scholars.
