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.

The whole world is an ashram in which all are doing sadhana. We must love the world, which is God's creation. Those who despise, hate and fear the world do not understand the intrinsic goodness of all.
