Descartes once said, “I think therefore I am”. Our minds are associated with our bodies. Our bodies eventually die and decay, so what happens to the mind when our bodies cease to function? Enter the soul, the last missing piece to who we are. The soul has also been called the heart or spirit. Many people believe that our souls are eternal; some will believe in heaven, others will believe in reincarnation, and some will believe in the combination of heaven and earth for eternity.
It is the soul that enters the body to form the mind. The soul stores are essence (who we are) as human beings. Descartes was partially correct in his assumption that we are our minds: but it is the soul that delivers vital information to the body, creating our individual minds, to think as we please. The soul carries are disposition of thoughts (not memories) from one lifetime to another, continuing our mindset for eternity. It is the action or non-action of these thoughts in our minds that determine if we have joy or suffering to our bodies. The following is from the Bible:
Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. King James Version of the Bible, Epistle to the Galatians, 6:7
Above all else, guard your soul/heart (against acting on negative thoughts),
for everything you do flows from it. International Version of the Proverbs 4:23
It is the soul that stores our negative acts as negative energy, and eventually will manifest (flows) these negative energies as suffering in the future. We reap what we have sowed. It is the soul that reminds us of the negative thoughts in our minds. We can remove these negative thoughts by not acting on the inconveniences that the soul manifests.
