Q. Why can we only have knowledge of God through the heart? What part of the mind does the heart represent?
A. The heart is the principle center, not the heart of the body, but the heart which is the depth of the mind, for the mind is the surface of the heart. The heart and mind are as one tree: the root is the heart and the branches; fruits, flowers, and leaves represent the mind. The heart is at the bottom of thought, imagination, and all. Feelings always belong to the heart, thought to the mind; so what belongs to the mind can be expressed in words, what belongs to the heart cannot. Everything in the mind is intelligible, but what is intelligible but not expressible, or beyond what is intelligible, that is the heart. Deeper feelings, mirth, kindness, sympathy, all fine feelings which cannot be expressed in words are all activities of the heart.
