The spirit soul is self-luminous. It looks like a luminous ball.
The spirit soul is inexhaustible, transcendental, pure, luminous, not covered by any matter. The spirit soul is a tiny fragment of God, a spark of His divine radiance, a particle of antimatter as subtle as a single spiritual atom, which makes it invisible to the human eye, for it is the size of one ten-thousandth of a hair's tip.
In truth, the soul has a spiritual body from which, like Lord Krishna, emerges a radiance that envelops it and thus gives it the appearance of a very beautiful luminous ball. This radiance is very strong, not blinding, and immaculately white. That is why seeing it is a real wonder.
The Lord says to this effect: The soul in the body is self-luminous and is separate from the gross body of visible dense matter and the subtle, ethereal, invisible body. This remains the fixed basis of the modification of bodily existence, just as the ethereal sky is the unchanging background of material transformation. This is why the soul is endless and without material comparison.
The spiritual soul alone illuminates the whole body with consciousness. Consciousness is the concrete proof of the presence of the soul in the body.
Consciousness is a manifestation of the soul, the main principle, the essence of the spiritual soul, the main energy of the soul, it is the soul itself. The soul is present in the heart of the living being, the celestial being, the human being, the animal and the vegetable, it is the source of all the energies that sustain the body. The energy of the soul is spread throughout the body, such is the consciousness, and it is thanks to the latter spread throughout the body that the soul manifests its omnipresence in the body in which it is found and which it keeps alive by its vital force.
Consciousness is also the perception that we have of ourselves, which allows us to say, “I am”.
The soul is the pure consciousness that expresses itself. It is the vital force, the active principle that allows the body to live and move. It is the true “I”, the conscious “I” and the true Ego. The true spiritual memory is in it. It gives the body its beauty and life. Each of us is, in truth, an eternal spiritual soul.
Let the soul leave the body, and the body collapses, inanimate, dead. Only the material bodies it borrows are subject to destruction. The body is nothing but a mass of inert matter, for it is naturally devoid of life. The body is a dead mass. It is the soul which temporarily resides in it, which gives it life. This tiny spiritual spark is the vital principle which animates the material body, where its influence is everywhere spread through this carnal envelope.
