By “the heart,” we do not mean the piece of flesh on the left hand side of our chest, which also is called “heart,” and which animals have, too. The heart proper to man is different. The heart is an invisible force. It is noticed through its effects. An electric current is not seen, either. But, because it causes the resistance wire to radiate light by heating it up when it passes through the bulb, we understand that it exists in the bulb. However, electricity is not matter. It does not occupy a place. And the force which we call “the heart” is not matter, either. It does not occupy a place. Since its effects are seen in a piece of flesh, which also is called the “heart,” we say that its place is in the heart. Endless Bliss First Fasicle | Page 280
