The sun is the heart of the system; so, also, the heart of man is the sun of the organism. There are many sun-hearts, and the Universe represents a system of hearts; therefore, the cult of Light is the cult of the heart. To understand this abstractly is to leave the heart cold; but as soon as the Light of the sun-heart shall live, the need of the magnet’s warmth will begin to shine forth like a true sun.
The heart’s rhythm can be regarded as the rhythm of life. The Teaching about the heart is as bright as the sun, and the warmth of the heart speeds as swiftly as a sunbeam. Everyone has wondered at the instantaneousness with which a ray of the rising sun warms all things. The heart can act likewise.
