 The BCA is associated with a famous legend of Śāntideva’s life, recounted by Butön (2013: 258–259) and often retold in Tibetan religious contexts. According to this account, the master Śāntideva was a student monk at the great monastic university of Nālandā, whose ruins can still be seen in the modern Indian state of Bihar. Unfortunately, to all outward appearances, Śāntideva was not putting any effort into the central activities expected of Nālandā’s students: the study and recitation of Buddhist religious and philosophical texts. He came to be known as a bhusuku, a kind of Sanskrit acronym derived from words meaning “eat”, “sleep”, and “defecate”—as that was all anyone had seen him do.
