The houses are clean and white, and great trees stand among them and spread over them. The fields lie around the town, divided by rows of such trees as stand in the town and in the woods, each field more beautiful than all the rest. Over town and fields the one great song sings, and is answered everywhere; every leaf and flower and grass blade sings. And in the fields and the town, walking, standing, or sitting under the trees, resting and talking together in the peace of a Sabbath profound and bright, are people of such beauty that he weeps to see them. He sees that these are the membership of one another and of the place and of the song or light in which they live and move.
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.
