I have heard that on one occasion the Blessed One (the Buddha) was living among the Sakyans. Now there is a Sakyan town named Sakkara. There Ven. Ananda went to the Blessed One and, on arrival, having bowed down to the Blessed One, sat to one side. As he was sitting there, Ven. Ananda said to the Blessed One, “This is half of the holy life, lord: admirable friendship, admirable companionship, admirable camaraderie.”
“Don’t say that, Ananda. Don’t say that. Admirable friendship, admirable companionship, admirable camaraderie is actually the whole of the holy life. When a monk (person) has admirable people as friends, companions, & comrades, he (they) can be expected to develop & pursue the Noble Eightfold Path.
