He was unsure as to what to do next, since he knew that what he had understood was so profound that it would be difficult for others to fathom. The god Brahma descended from his heaven and asked him to teach, pointing out that humans are at different levels of development, and some of them would benefit from his teaching. Consequently, the Buddha concluded that the most suitable students would be his first teachers of meditation, but he was informed by a deity that they had died. He thought next of his five former comrades in the practice of asceticism. The Buddha determined through his clairvoyance that they were residing in a deer park in Sarnath, outside Varanasi (Banaras). He set out on foot, meeting along the way a wandering ascetic with whom he exchanged greetings. When he explained to the man that he was enlightened and so was unsurpassed even by the gods, the man responded with indifference.
