Tirukkural 174: Not Coveting

The wise who have conquered their senses and are free from crime, will not covet (the things of others), with the thought "we are destitute".

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.
—Gurudeva
