Question: Could you explain further how the mind is the surface of the heart, and the heart the depth of the mind.
Answer: There are five fingers but one hand, there are several organs of the body but one body, and there is a universe full of variety but one Spirit. So there is one heart which feels the various thoughts and imaginations which spring up and then sink into it. The bubbles are to be found on the surface of the sea. The depth of the sea is free from bubbles. The commotion is to be seen on the surface, the depth of the sea is still. The mind is the commotion of that something which is within us, that something which we call heart.
