God tells us that we do not know the soul (heart). Although, there are many references to the heart or soul in our sacred books, we do not know very much about the soul. We cannot qualify or quantify it with science. Since we cannot identify it, we do not know when life starts or when the soul enters our bodies.
In our religion, we believe that the soul is the pure positive energy that carries our debts from our past lives. Some will have much debt surrounding the pure heart, while others will have no debt, allowing the pure heart to bring upon joy.
These debts eventually manifest as sufferings, illness or inconvenience in our lives. Like the DNA that carries information on our genetic makeup, our soul carries our fate. Where is the origin of our debts that the soul continues to collect? This origin is from our minds. It is our negative thoughts of greed, arrogance, and self-love that the soul collects as negative energy, and will eventually release as sufferings; it is as if the soul maintains its own justice in the cycle of life and death. We sow what we reap. But these debts do not immediately manifest, causing us to blame others.
How do we get away from this cycle of suffering that the soul carries, and how do we prevent evil thoughts from emerging in our minds. First of all, we must not look for others to blame when inconvenience or suffering appears. We must not kill the messengers that come to collect our debts. We must calm our minds and not take action on our evil thoughts that may emerge from our minds when these sufferings or temptations occur. If we continually suppress these evil thoughts, these thought will eventually subside. For some, whose soul is surrounded by much debt, this process of purification will take time, and much dedication. God promises that this path is not easy; but if we follow it, our souls will become uncovered of debt, and our future will only be joyous.
