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.

Grace has come to us in unexpected ways in the midst of life. We have known healing, courage, restored love — salvation. From these blessings of grace we see how to live in resistance to violence; we see how to live in love and in truth without denying bitter realities. We have felt a fire in the heart of things, intimated in moments of surprise, a power which guards, judges, and continually recreates life. We have sensed what Wordsworth called "a presence that disturbs me with joy ... something far more deeply interfused." This presence, felt as mystery and offered as faithfulness to one another, sustains and heals life. It calls for justice.
