Then a certain monk approached the Blessed One, etc.
Seated to one side, that monk said this to the Blessed One:
"What, venerable sir, is the cause, what is the condition, whereby some womb-born serpents here observe the Observance and become ones who have relinquished their bodies?"
"Here, monk, etc.
This, monk, is the cause, this is the condition, whereby some womb-born serpents here observe the Observance and become ones who have relinquished their bodies."
