Because the ‘I am’ principle is there, it is moving all over. To recognize it, you put on various uniforms in order to give it identity, but the principle is already there, and because of that principle you are engaging in various activities. Unless you wear the uniform (the body) you will not be able to conduct any activities. Once you discard this ‘I amness’ uniform, what remains is the ‘Parabrahman”. That which is eternally current is the ‘Parabrahman’.
