Unless we are rooted in God, and rooted in the only sure way of listening to God -- namely, silence -- then we are doomed to spend our lives standing at the window of life and watching the world go by... It strikes me that most of the first part of our lives is spent filling our heads with information. The last part -- and the most important part -- is spent emptying our heads of all the trivia so that our hearts may be free to learn wisdom -- in silence.
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.
