Our understanding of ātma (our Self) has to grow through several stages. At first we believe that consciousness is within the body, identifying with the physical body as the primary source of one's individuality. Our next level of understanding is, the same consciousness that is in my body, is present in all other people & beings also. Then we understand that consciousness is not only within the body's; but is all pervading. Consciousness appears discreet because it is recognised only when it is manifest as life in living beings. That means everything is within consciousness. All things we experience are appearing upon consciousness. This understanding acknowledges that consciousness is not limited to individual beings but is the fundamental essence of the creation itself. AND THAT CONSCIOUSNESS I AM. The individual self is seen identical with all pervading Brahman.
