Tirukkural 364: Freedom from Desires

Purity (of mind) consists in freedom from desire; and that (freedom from desire) is the fruit of the love of truth.

Image of Satguru Sivaya Subramuniyaswami
There is another way to show remorse for misdeeds. That is by performing seva, religious service, for persons you have wronged. Give them gifts, cook them food.
