You know, O my God, I have never desired anything but to love You, I am ambitious for no other glory. Your love has gone before me, and it has grown with me, and now it is an abyss whose depths I cannot fathom. Love attracts love and my love leaps toward yours; it would like to fill the abyss which attracts it, but alas; it is not even a drop of dew lost in the ocean! For me to love You as You love me, I would have to borrow your own Love.
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.
