Before details of this case, may I return to the first year. In the first year of the Buddhs’s Enlightenment, He had given the first sermon called Dhammacakkappavattana-Sutta to the five ascetics, at Isipatana, Baranasi, India. In this sermon, the Buddha got the first follower his name is Kndanna, the leader of five ascetics. He, (Kondanna) got the vision of Dhamma (Dhammacakkhu), after that, the Buddha had given discourse (sutta) its name is Anattalakkana-sutta (non-self sutta) to the five ascetics (Pancavakki) and another sutta named Anuppikatha with Caturariyasacca for Mr. Yasa and amount of 54. Finally, the Buddha had given the sermons to two groups namely;-
1. The group of five ascetics and
2. The group of Yasa and his 54 friends
Both groups numbering 60 attained Arahant ship, free from defilements, they are the first Sangha followers of the Buddha.
