Tirukkural 312: Not Doing Evil

It is the determination of the spotless not to do evil, even in return, to those who have cherished enmity and done them evil.

Performing daily sadhana, keeping good company, pilgrimaging to holy places, seeing to others' needs--these evoke the higher energies, direct the mind to useful thoughts and avoid the creation of troublesome new karmas.
