In the tenth chapter of the Madhyamakahṛdayakārikā, which consists of 14 verses, Bhāviveka, rejecting the Jain view that some episodes of the Buddha’s life tell us of his ignorance, tries to prove the Buddha’s omniscience （sarvajñatā）. Madhyamakahṛdayakārikā 10.12-14 deals with the following two episodes: that the Buddha allowed Devadatta, who subsequently tried to kill the Buddha and cause a schism in the saṃgha, to be ordained as a monk; and that the Buddha allowed Sunakṣatra, who subsequently returned to the lay life and abused the Buddha, to be ordained as a monk and had him as an attendant. The Jain opponent argues that the Buddha is not omniscient because he could not foresee their future behavior when he allowed them to be ordained as monks. Bhāviveka answers this objection by showing how the Buddha foresaw their future behavior, based on the Mahāparinirvāṇa-mahāsūtra 大般涅槃経, not the Upāyakauśalyasūtra 善巧方便経, which Kawasaki 1992 regarded as the source. According to Bhāviveka, the Buddha could foresee that （1） if Devadatta were not to become a monk, he would become a king and destroy the Buddha’s teachings; but （2） if he were to become a monk, he could not do anything to the Buddha. He also foresaw that Sunakṣatra could accumulate merits （puṇya） while he served as an attendant of the Buddha.
