“The soul is the contact unit of the inflow and outlet of infinity. Some say the soul is in the heart, some say the soul is in the solar plexus, some say it is in the brain. But do you know where the soul is? It is the circumvent force around the body, which mystics call the arc of life. Aura is the outer projection and arc is the inner projection. The arc is the point of contact between the astral body and the gross body.” Yogi Bhajan
