That which none breathes with the breath, but by which breath is in-breathed: know that alone to be the Brahman, not this which people worship here.

Ordinarily we know three states of consciousness only,—waking, dreaming and sleeping. There is, however, a fourth state, the superconscious, which transcends these. In the first three states the mind is not clear enough to save us from error; but in the fourth state it gains such purity of vision that it can perceive the Divine. If God could be known by the limited mind and senses, then God-knowledge would be like any other knowledge and spiritual science like any physical science. He can be known, however, by the purified mind only. Therefore to know God, man must purify himself. The mind described in the Upanishads is the superconscious mind. According to the Vedic Sages the mind in its ordinary state is only another sense organ. This mind is limited, but when it becomes illumined by the light of the Cosmic Intelligence, or the "mind of the mind," then it is able to apprehend the First Cause or That which stands behind all external activities.
