Suppose there is a soul, or a spark of life that begins our existence in our physical body. Some may call it the inner most heart, which is pure and positive in its original state. In the Tip of the Writing brush is a verse that identifies the heart (soul) as the sand that filters our evils (greed, arrogance, and self love) thoughts. Like the sand that purifies our sewage system, the positive heart (soul) functions to attract our negative thoughts, and store these evils.
Imagine without our soul (heart) containing many of our evil thoughts, how much suffering will result from our evil thoughts going into action. Our soul, in essence acts as our conscious, and limits our evil action. The heart by tying up these negative evils prevents these negative energies from traveling to other parts of our bodies causing immediate injury and sickness. But these negative energies stored or contained in the heart will eventually cause destruction if the mind continues to produce evil thoughts. It is said that these negative energies are gradually released causing suffering (karma or cause and effect) or disease of the body. What is planted in the heart will eventually sprout.
It is only when our hearts are pure, that we can avoid the sufferings that result from the release of negative energy from the evils in our hearts. When our thoughts become positive, the heart or soul will eventually becomes free of evil. It is this goal of having good thoughts that we must strive for. We must be light hearted, and not have a heavy heart which will burden us in the future.
It is with this information that we pray to God to sweep the evils from hearts of the world. God is said to help us remove these evils imbued in our heart, but has no influence over our minds. It is for us to eliminate evil (greed, arrogance, and self love) thoughts from our minds to lighten our hearts. When this happens, our innermost hearts returns to purity, and our future will be only joyous with everyone helping each other.
