Silence is a privileged entry into the realm of God and into eternal life. There is a huge silence inside each of us that beckons us into itself, and the recovery of our own silence an begin to teach us the language of heaven. For, silence is a language that is infinitely deeper, more far-reaching, more understanding, more compassionate, and more eternal than any other language... There is nothing in the world that resembles God as much as 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.
