According to my beliefs, the
nature of the soul is a mystery.
“Thou hast asked Me concerning the nature of the soul. Know, verily, that the soul is a sign of God, a heavenly gem whose reality the most learned of men hath failed to grasp, and whose mystery no mind, however acute, can ever hope to unravel. It is the first among all created things to declare the excellence of its Creator, the first to recognize His glory, to cleave to His truth, and to bow down in adoration before Him. If it be faithful to God, it will reflect His light, and will, eventually, return unto Him. If it fail, however, in its allegiance to its Creator, it will become a victim to self and passion, and will, in the end, sink in their depths.”
Gleanings From the Writings of Bahá’u’lláh, pp. 158-159
However, the
function of the soul can be known.
The soul animates the body and gives it life. The soul communicates its desires through the brain to the physical body, which thereby expresses itself, so the soul is responsible for the mind, senses and emotions as well as physical sensations. The soul, working through the brain, is responsible for all our thought processes.
The body needs a soul to direct its processes, but the body is just the medium through which the soul functions while we are alive on earth in a physical body. The soul is our true self, the sum total of the personality, the person himself; the physical body is pure matter with no real identity. The person, after he dies and leaves his physical body behind, goes to the spiritual world where the soul takes on a spiritual body made up of heavenly elements that exist in the spiritual realm. Since all we have ever experienced is physical, it is impossible for us to understand what it is like to be living as a purely spiritual being rather than a physical body.
