Linked Discourses 45.2 1. Ignorance Half the Spiritual Life

So I have heard. At one time the Buddha was staying in the land of the Sakyans, where they have a town named Townsville. Then Venerable Ānanda went up to the Buddha, bowed, sat down to one side, and said to him: “Sir, good friends, companions, and associates are half the spiritual life.”

“Not so, Ānanda! Not so, Ānanda! Good friends, companions, and associates are the whole of the spiritual life. A mendicant with good friends, companions, and associates can expect to develop and cultivate the noble eightfold path.
