It is human nature to deny that one is at fault. For example, it is difficult for an alcoholic or gambler to admit their compulsions. Many will agree that without their admission of a problem, they will continue to regress.
The law of causality is also difficult for people to accept. The law of causality states that good thoughts and behaviors set forth a joyous future, and evil thoughts and behaviors set forth sufferings in the future. When sufferings occur, we scoff at the idea that they result from our past sins. We deny our faults. We do not want to admit that our loved ones or we have sinned or have behaved poorly in past lives. We have a difficulty accepting this self-regulating concept of purifying our minds. We are not at fault for our sufferings.
But like the gambler or the alcoholic, we must face our tormenters. We must admit that we have sinned. We must accept the law of causality as a self-regulating process of purifying the minds. Understanding causality puts the onus on us, instead of blaming others for our sufferings. We are not perfect, but we can be perfect by understanding and applying the principles of causality. Causality gives us an opportunity to create a joyous life. It is a simple philosophy; be good, and you will have joy.
