I invented what I call the Invisible Art and Light technique. In normal light the painting appears one way, and when you turn on the black lamp, the beams of light emerge. It is also a brilliant metaphor. If we look with our physical eyes we see only the surface of the message. But when we look with our spiritual eyes we see so much more. We see the light that is given as a gift from Heaven. And isn't it interesting that a black light is used to see the whole picture? In the same way we must go into our own darkness, the things we hide because we are ashamed, in order to unleash the light within. It is only when we give our whole selves to God--the positive and the negative--that we are enlightened.
Mystical prayer is essentially an experience of unity with God and God's creation. Kything is a gateway to mystical experience and can foster deeper prayer states. When you kythe you transcend separateness without losing your identity. When you kythe you enter into a state of unconditional love and spiritual union.
As a hasidic master once wrote about experiencing this spiritual energy while kything with nature:
When you walk across the fields with your mind pure and holy, then from all the stones, and all the growing things, and all animals, the sparks of their soul come out and cling to you, and then they are purified and become a holy fire in you.
