The bodies comprise five organs of perception, five organs of action, and the mind, but these are in reality only inert matter. Because it is only a mass of matter, the brain does not have the power to act on its own. It can only function when it receives the energy of the Supreme Lord.

Krishna, God, the Supreme Person, activates and enlivens the material body, the senses, the vital breath, the heart, and makes them come alive. Without the Lord, the living being is nothing and can do nothing. He cannot see, hear, smell, feel, taste, or act without the active principle, God. By entering the body of every living being in His form as the Supreme Soul, God animates the material body, the senses, the life airs, and the mental activities, and thus the ethereal and dense material organs begin their functions.

Consciousness is the energy of the soul, and it is spread throughout the body by the red blood cells that make up the blood circulating within it.

The soul floats, carried by the five types of air: prana, apana, vyana, samana, and udana. Situated in the heart, it dispenses its energy, consciousness, to the entire body. Once purified from the contamination of these five types of material air, it reveals its spiritual power.

The soul is the vital principle of the material body, where its influence is spread everywhere. Consciousness manifests itself by exerting its influence throughout the body; it is proof of the presence of the soul, which is its source. All those who are enlightened by knowledge of the principles of spiritual science know that a body deprived of consciousness is a lifeless object that nothing can revive.

In truth, the energy of the soul spread throughout the body is what is called consciousness. It is because consciousness is spread throughout the organism that the being experiences sensations of pain or pleasure in each part of its body.

If the soul (each of us is in truth an individual soul distinct from God) is the possessor of the body in which it has incarnated, let us understand that God is the Supreme Possessor.

In truth, despite its infinitesimal size, the soul measures only one ten-thousandth of the tip of a hair, yet it possesses great power that allows it to operate the body, and by its vital force to keep it alive. Should it leave the body, the latter collapses lifeless.

The soul is in reality a spiritual atom, a particle of spiritual energy also called a spiritual spark, a tiny fragment, an integral part of the Supreme Person, Krishna.
