There are two aspects of vibrations, fine and gross, both containing varied degrees. Some are perceived by the soul, some by the mind, and some by the eyes.

• What the soul perceives are the vibrations of the feelings;
• what the mind conceives are the vibrations of the thoughts;
• what the eyes see are the vibrations solidified from their ethereal state and turned into atoms which appear in the physical world, constituting the elements ether, air, fire, water and earth.
• The finest vibrations are imperceptible even to the soul. The soul itself is formed of these vibrations; it is their activity which makes it conscious.
