Then a certain devata, in the far extreme of the night, her extreme radiance lighting up the entirety of Jeta's Grove, went to the Blessed One. On arrival, having bowed down to him, she stood to one side. As she was standing there, she said to the Blessed One, "These seven qualities, lord, lead to a monk's non-decline. Which seven? Respect for the teacher, respect for the Dhamma, respect for the Sangha, respect for training, respect for concentration, respect for heedfulness, respect for hospitality. These seven qualities, lord, lead to the non-decline of a monk."

There is the case where a monk himself has admirable friends. He speaks in praise of having admirable friends. With regard to those other monks who don't have admirable friends, he gets them to undertake admirable friendship. As for those other monks who do have admirable friends, he at the proper times speaks in praise of them — truly, accurately.
