I think that when I die, I can breathe back the breath that made me live. I can give back to the world all that I didn't do. All that I might have been and couldn't be. All the choices I didn't make. All the things I lost and spent and wasted. I can give them back to the world. To the lives that haven't been lived yet. That will be my gift back to the world that gave me the life I did live, the love I loved, the breath I breathed
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.
