Shantideva was a scholar in the eighth century from the monastic university Nalanda, one of the most celebrated centers of learning in ancient India. According to legend, Shantideva was greatly inspired by the celestial bodhisattva Manjushri, from whom he secretly received teachings and great insights. Yet as far as the other monks could tell, there was nothing special about Shantideva. In fact, he seemed to do nothing but eat and sleep. In an attempt to embarrass him, the monks forced Shantideva's hand by convincing him to publicly expound on the scriptures. To the amazement of all in attendance that day, Shantideva delivered the original and moving verses of the Bodhicharyavatara. When he reached verse thirty-four of the ninth chapter, he began to rise into the sky, until he at last disappeared. Following this, Shantideva became a great teacher.
