This teaching, the Mutual Possession of the Ten Realms, brings us various enlightenments. Take “Love” for example. Love is a very important factor in human relationships. According to this teaching, love cannot exist alone. Love consists of emotions such as joy, sadness, hope, ego, respect, anger, doubt, and hatred. Therefore, love has the potential to transform suddenly into hatred or anger. Sometimes love transforms itself into jealousy by mixing with anger, doubt, and ego. With joy, ego, and anger, love can become abusive. We should keep this in mind and have great patience in our relationships with one another, otherwise, we will not be able to tolerate the unexpected changes in others.
