"The Bhikkhu Ananda approached me, paid homage to me, sat down to one side, and said:
Venerable sir, this is half of the holy life, that is, good friendship, good companionship, good
comradeship." Then the Buddha said, "Not so, Ananda! Not so, Ananda! This is the entire
holy life, Ananda, that is, good friendship, good companionship, good comradeship. When one
has a good friend, a good companion, a good comrade, it is to be expected that he will develop
and cultivate the Noble Eightfold Path."
Samyutta Nikaya 3.18
