Vutthi Sutta
A conversation between two devas and the Buddha’s comments thereon.
The first deva asks questions, which the second answers:
“Seeds are the best of things that rise up, rain is the best of things that fall down, cattle are the best of things that walk, and sons are the best of those who speak out.”
“Of things that rise up, knowledge is the best; ignorance is the best of those that fall down, the Saṅgha is the best that walk (for alms), the Buddha is the best of those who speak out.” S.i.42.
