My daughter, three years old and fearless, loves nothing more than wading along the shallow shoreline outside our house. Holding hands, we walk barefoot upstream quietly in the water, stepping delicately over stones. Besides the water sounds, there is just immense silence. We stop and listen to the water. She asked me for a story; I did not have one. Listening, she turned in delight and announced, "Daddy, this water is talking." In listening to the river a kind of silence prevails, broken only by the rush of water over rocks. Such a silence is more like faint echoes, each a series of dim reverberations. They continue in you, distant yet familiar.
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.
