As long as the soul is not still, there can be no vision. But when stillness has brought us into the presence of God, then another sort of silence, much more absolute, intervenes: the silence of a soul that is not only still and recollected, but which is overawed in an act of worship by God's presence.
The spirit, by its very nature, is Slow. No matter how hard you try, you cannot accelerate enlightenment. Every religion teaches the need to slow down in order to connect with the self, with others and with a higher force. In Psalm 46, the Bible says: "Be still then, and know that I am God."
