We human beings are in search of meaning, in search of our selves. Very little of what we already are and already have brings us deeper meaning or happiness. We are born for meaning, not pleasure, unless it is pleasure that is steeped in meaning. And we are born as well for suffering, not the suffering that leads to madness but the suffering that leads to joy: the struggle with ourselves and our illusions. We are born to overcome ourselves, and through that overcoming to find an inner condition of great harmony and being. We are born for that—we are not yet that. We are searchers; that is the essence of our present humanness.
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.
