In order to listen to God's silence we must escape the din of distractions that normally deafen us to it. Being deafened to the silence within as well as the silence without is corrosive to God-hearing. To be silent is to so empty oneself of the din of transitory distractions that one becomes fully receptive to the silence that always and everywhere underlies them. Silence is that state of spiritual sensitivity in which seekers make themselves available to the silence of God's voice.
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.
