“Consciousness is originally pure, like water. But if we mix water with a certain color, it changes. Similarly, consciousness is pure, for the spirit soul is pure. But consciousness is changed according to the association of the material qualities. Real consciousness is Krishna consciousness. When, therefore, one is situated in Krishna consciousness, he is in his pure life.” (Shrila Prabhupada, Bhagavad-gita, 15.9 Purport)
