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
The good-and-bad concept should be thrown out with a lot of other things, including the up-and-down concept. There is no good; there is no bad. You don't raise your consciousness, nor do you lower it.
—Gurudeva
