Shankara

 The nature of the Self, as pure Awareness, is Eternity, Purity, Reality, Consciousness, and Bliss. When the Self gets confused with body and mind it is overcome by mortal fears. The Self regains fearlessness by realizing the Truth about Itself.

Awareness does not need another instrument, like the mind, to be aware of Itself. The Self is not this or that but Itself. The Self is without attributes and action. The Self is changeless, eternal, pure, and free. The Self is pure Awareness as God is pure Awareness. Pure Awareness is without a second.

He who has attained the Supreme Goal dwells as the embodiment of Infinite Consciousness and Bliss. The practice that destroys ignorance is constant meditation. Because of ignorance the ever-present Awareness is not recognized. The seeker who has realized the Self sees the entire universe as the Self
