7.40

“Is he the son of devaputras
in the heavens above,
or among the nāgas,
the son of a nāga spirit?”
Then the Buddha himself explained:
“He is not the son of devaputras,
nor is he your son,
nor is he the son of the nāgas.
All causes and conditions of birth and death
are impermanent, like an illusion;
nothing endures for long,
just like a passing guest.”
