Kamma

[Uttara the deva's son:]

"Life is swept along,
next-to-nothing its span.
For one swept on by aging
	no shelters exist.
Perceiving this danger in death,
one should do deeds of merit
	that bring about bliss."

[The Buddha:]

"Life is swept along,
next-to-nothing its span.
For one swept on by aging
	no shelters exist.
Perceiving this danger in death,
one should drop the world's bait
	and look for peace."
