Having attained Buddhahood, the supreme state of perfection, Buddha devoted the remainder of his precious life to serving humanity, both by example and precept, without any personal motive whatsoever. In order to deliver his first sermon the Buddha started for Benares.
(The place where his first five disciples greeted Buddha.)
At Benares he met Kondanna and his four companions in the Deer Park, now known as Saranath.
Then he preached them his first great sermon, the Dhammacakkapavattana Sutta, in which he explained the Four Noble Truths and the Noble Eightfold Path. They received ordination and formed the first nucleus of the holy brotherhood of disciples known as the Sangha.
(The place where Buddha preached his second sermon.)
Three months after the first sermon, Buddha gave his second sermon to his first five disciples and they all attained Nirvarna, a morally perfect state.
Sarnath, where the Buddha preached his first sermon in the Deer Park (Migadavon), is 10 km from Varanasi_ the city of Varanasi is situated along the west bank of the Ganges in the north Indian state of Uttar Pradesh;called Benaras by the British_ and it has most impressive remains, as well as a modem temple.
