Only those who consider the Soul to be at one with the body, and who think the several orders and modes of life to be really different from one another, commit the inistake of supposing an intermingling to be possible. My body is different from yours. But my soul is not different from your soul. When I am able to realise this, I have not the least doubt that my understanding is really not living in yours, though I have entered into you by Yoga.
