There is no fear in love, but perfect love casteth out fear. Fear is a painful emotion that arises at the thought that we may be harmed or made to suffer. As long as we must trust for survival to our ability to out look or out maneuver the enemy, we have every good reason to be afraid. Fear is torment. To know that love is of God and to enter into the secret place leaning upon the arm of the Beloved, this and only this can cast out fear.
Take hold of your own life. See that the whole existence is celebrating. These trees are not serious, these birds are not serious. The rivers and the oceans are wild, and everywhere there is fun, everywhere there is joy and delight. Watch existence, listen to the existence and become part of it.
