The famous YouTube channel(s) where we believe they are sastric are advocating shlOkam as prAyaschiththam for something done to someone

How?

If you harm someone & tell ShlOkam

Vishnu will cleanse?

See praying Vishnu is first step to resolution

Ask sorry to same person to whom you comitted mistake

That is cmed BhAgavatha Dharmam

BhAghavatha apachAram cannot be forgiven by Vishnu himself in fact he is incapable of doing so

Vishnu makes it a point wherever possible to teach us

The SharanAgathi concept is also same
Once you self surrender Vishnu takes the responsibility to sort it out as softly as possible

Theeyinil thoosagum

See, burning is an act but fast enough to erase
