Cattāri Brahmavihārā

AN 2.136:

Bhikkhus, on account of the wrong behaviour towards two, the not learned foolish man destroys himself, becomes blameable and blamed by the wise, accures much demerit. Who are the two? They are mother and father.

Bhikkhus, on account of the right behaviour towards two, the learned Great Man does not destroy himself, does not become blameable and praised by the wise, accures much merit. Who are the two? They are mother and father.

Visiting my father today and I was lucky enough to find these verses.
