There was a topic on misdeeds and atonements in the previous Sudarshanam issue. Due to time, place and the current pandemic outbreak we could not perform certain rituals; how to atone for such misdeeds? Please clarify.

In general, we atone by submitting our prayers to Perumal seeking His pardon. One does it exclusively by performing prayaschitta sharanagati.
Scriptures have provided atonements for each misdeed. If we are aware of the misdeeds, then we can atone accordingly, or we can recite the following verse from Swami Desikan’s Nyasa Dasakam and pray to Perumal as such for atonement.
