Sattva, Rajas and Tamas
The states of sattva, rajas, and tamas come from me, but I am not in them. These three gunas deceive the world: people fail to look beyond them to me, supreme and imperishable. The three gunas make up my divine maya, difficult to overcome. But they cross over this maya who take refuge in me. Others are deluded by maya; performing evil deeds, they have no devotion to me. Having lost all discrimination, they follow the way of their lower nature.
Bhagavad Gita 7:12-15
