What is the human soul?

A great natural law breathed into you the breath of life and you became a living soul.

The germs of all things that live reside within the ethereal atmosphere, which interpenetrates all space.

All life came from the atmosphere—the germs of all things that live reside within the atmosphere, not the coarser air, but the ethereal atmosphere, which interpenetrates all space.

The great Law of Involution gave you life, and at the death of the body, the spirit goes back into the ethereal atmosphere or the celestial world.

When you are sitting quietly in a room, look toward the light of a window, look out of the window toward the sky, but let your gaze rest steadily upon the atmosphere a few yards from the eyes—do not look at anything, but the air—gaze quietly and steadily for a few moments and you will thus behold the germinal sea, consisting of living, germinal points of light.

These points of light, which you will see are living little globes, lighter in colour than the atmosphere, of all grades and sizes, and they are darting hither and thither in all directions, filled with life and motion, never still for an instant, little, bright, translucent globes of light, an unending sea of germinal life to be seen with the naked eye.
