Knowledge of the Absolute depends upon no book, nor upon anything; it is absolute in itself. No amount of study will give this knowledge; is not theory, it is realization. Cleanse the dust from the mirror, purify your own mind, and in a flash you know that you are Brahman.
Swami VivekanandaThe body is the external coating and the mind is the internal coating of the Atman who is the real perceiver, the real enjoyer, the being in the body who is working the body by means of the internal organ or the mind.
Swami Vivekananda
