This was said by the Lord…

“Bhikkhus, in regard to external factors, I do not perceive another single factor so helpful as good friendship for a bhikkhu who is a learner, who has not attained perfection but lives aspiring for the supreme security from bondage. Bhikkhus, a bhikkhu who has a good friend abandons what is unwholesome and develops what is wholesome.”

When a bhikkhu has good friends,
And is reverential and respectful,
Doing what his friends advise,
Clearly comprehending and mindful,
He may progressively attain
The destruction of all fetters.
