The mind is not the brain. The mind is a capacity, an Akasha, which contains all the experiences we have in life, all the impressions we gain through our five senses. It is not only within the body but also around the body. But the centers of perception reflect every thought and feeling, and then man feels that the mind is within him. In point of fact the body is within the mind, and the mind within the body. As the eye sees an object before it, so the centers of perception reflect every thought and feeling. For instance man feels the sensation of joy and depression in the center called solar plexus; however, this does not mean that joy or depression is there, but that this center is sensitive to such experiences.
