DN 31 states:
A child should serve their parents as the eastern quarter in five ways, thinking:
Pañcahi kho, gahapatiputta, ṭhānehi puttena puratthimā disā mātāpitaro paccupaṭṭhātabbā—‘I will support those who supported me. I’ll do my duty for them. I’ll maintain the family lineage. I’ll take care of the inheritance. When they have passed away, I’ll make an offering on their behalf.’
bhato ne bharissāmi, kiccaṁ nesaṁ karissāmi, kulavaṁsaṁ ṭhapessāmi, dāyajjaṁ paṭipajjāmi, atha vā pana petānaṁ kālaṅkatānaṁ dakkhiṇaṁ anuppadassāmīti.
I’ve been trying to find references for the last item, making offerings on behalf of one’s deceased parents, but it seems to imply some kind of benefit (To oneself? To one’s deceased parents?).
Is there any other sutta or commentarial text that explains this concept (of making offerings on behalf of others) in detail? I’ve read some discussions in the forum about the transference/sharing of merit, and it seems to point towards it being only attested for pretas rather than of general application as in Mahāyāna schools.
I would want to know if there’s any benefit to this at all, whether that be for oneself, for the ones you’re making offerings on behalf of, etc., and why it is important for a child to do so for one’s parents.
There’s a separate thread on this from 2017, but it didn’t get any discussion, unfortunately.
