2.2

the Bhagavān has taught the followers of the Śrāvakayāna and the Pratyekabuddhayāna that the prātimokṣa vows are the pure training and superior ethical discipline. The Bhagavān has also taught that followers of the Bodhisattva­yāna do not abandon their training even for the sake of their lives.⁴⁰ How then would a bhagavān, one who has either passed into parinirvāṇa or still remains, explain the prātimokṣa vows of the followers of the Śrāvakayāna? How would the prātimokṣa vows of the followers of the Pratyekabuddhayāna be explained? How would the prātimokṣa vows of bodhisattvas who follow the Mahāyāna be explained? The Bhagavān has said that I am supreme among those who uphold the Vinaya. I will certainly listen closely to the Bhagavān’s expertise in the Vinaya and, having mastered it precisely, will gain fearlessness and teach it perfectly and in detail to the assemblies. Therefore, I thought to ask the Bhagavān to teach me perfectly and in detail.⁴¹

“Bhagavān, while I was alone in private meditative seclusion, I thought, ‘I should go before the Tathāgata and request a detailed explanation of the Vinaya.’ Since this thought came to mind, Bhagavān, I ask the Tathāgata to offer a clear, thorough, and detailed explanation of the Vinaya to this great assembly of monks and bodhisattvas.”

The Bhagavān responded to the venerable Upāli, “Upāli, you should say that the training of the followers of the Śrāvakayāna is pure in terms of its distinctive application and distinctive orientation.
