As he was seated to one side, Ven. Ananda said to the Blessed
One, "This is half of the holy life, lord: having admirable people
as friends, companions, & colleagues."
"Don't say that, Ananda. Don't say that. Having admirable people as
friends, companions, & colleagues is actually the whole of the
holy life. When a monk has admirable people as friends, companions,
& colleagues, he can be expected to develop & pursue the
noble eightfold path.
"And how does a monk who has admirable people as friends,
companions, & colleagues, develop & pursue the noble
eightfold path? There is the case where a monk develops right view
dependent on seclusion, dependent on dispassion, dependent on
cessation, resulting in letting go. He develops right resolve...
right speech... right action... right livelihood... right effort...
right mindfulness... right concentration dependent on seclusion...
dispassion... cessation, resulting in letting go. This is how a
monk who has admirable people as friends, companions, &
colleagues, develops & pursues the noble eightfold path.
"And through this line of reasoning one may know how having
admirable people as friends, companions, & colleagues is
actually the whole of the holy life: It is in dependence on me as
an admirable friend that beings subject to birth have gained
release from birth, that beings subject to aging have gained
release from aging, that beings subject to death have gained
release from death, that beings subject to sorrow, lamentation,
pain, distress, & despair have gained release from sorrow,
lamentation, pain, distress, & despair."
