No swamy; re-do of prapatti is not required.

If we genuinely regret our mistake and express our apology to the person(s) affected by our sin, then the apparent hurdles on the path of prapatti will disappear. If the person(s) affected by our mistake are not accessible for communication, then we can express our regret and apology to our acharyan.

Wrong answer.

One cannot do mistake to one bhAgavatha & show regrets to AchAryan

Perumal will let the BhAgavatha apachAram to sort it out some way. It may be next janma. That’s why Swamy Desikan says “BhAgavatha ApachAram the only hurdle to Moksham”

One has to undergo extreme pain for BhAgavatha ApachAram example Seetha Piratti fire bath.

Though prapatti is done only once

I have seen one maami doing

“PrAyaschitha Prappatti”

In Andavan ashramam

I don’t know the intricacy

This I have already recorded in dharma sandeha in past

Actually that maami/old paati was crying before 2nd Prappatti. Told “I have committed many Sins don’t know what to do”.

That scene is still in my eyes.
