Brahman, the eternal soul, was never born and will never die, nor does it grow or decay. That spiritual soul is actually the knower of the youth, middle age and death of the material body. Thus the soul can be understood to be pure consciousness, existing everywhere at all times and never being destroyed. Just as the life air within the body, although one, becomes manifest as many in contact with the various material senses, the one soul appears to assume various material designations in contact with the material body.
