Individuals live, as in a cell, in the narrow world of the words they utter -- every individual and every group. Words are no longer bridges linking the one to the other. Speech which is not heard only intensifies isolation and increases the babel of tongues. the clever ones profit by this. Less and less a helpful servant and more and more an instrument of propaganda, speech has become the vehicle for uneasy consciences. Words must be purified in a redemptive silence if they are to bear the message of peace ... For, a soul gathered in silent worship is never alone with God. It is always in communion with the soul of all other worshippers; its plunges it into that inward light which lightens every person."

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.
