If a person interpolates scriptures with a good intent e.g., by replacing offending/controversial words/verses that are not current with the times, but doesn't disclose the modifications to maintain the authority of the scripture over the masses, does the person gain any puṇya by doing so?
Similarly, if one alters scriptures with a malicious intent, e.g., by inserting an authentic sounding verse in an important scripture for personal gains e.g., to prove superiority of one Hindu sect over the other, or a king could secretly sponsor additions to Manusmṛti so he can maintain tighter control over his subjects, does it constitute a sin?
