When you live life from your center, you operate from the indwelling spirit outwards into the visible world, like the spokes of a wheel, radiating God's love, wisdom and power. This is what is meant by being in the world but not of it. You remain calm in a crisis. You carry this calmness with you through the ordinary activities of the day, even when things go wrong... Centered in peace, you experience JOY... This is the culmination of growth in being. What you ARE, far more than what you say or do, will be the witness of your faith.
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.
