If you must think in terms of reward and punishment, consider that you will be abundantly rewarded for thoughts and acts of love and compassion. You will be invariably punished for acts of hatred and violence. We are spiritual beings in a vast spiritual sea, populated by innumerable other spiritual beings. Some are in physical form, but most are not. Love is the water of this sea.
Love is an energy, the highest and most pure energy.
At its highest vibrations love possesses both wisdom and awareness. It is the energy that unites all beings. Love is an absolute and it never ends. Healing energy is a component of spiritual energy. With future research and improved technology, we will better understand this connection.
