There is no progress in prayer without progress in faith, a purification of faith. And this entails the removal of all the props which depend on human endeavor, human reasoning, signs and the rest. It is the naked faith which is a terrifying experience and yet is the meeting point ultimately between God and ourselves in the depth of our being. This experience of the purification of faith is not normally one which comes early in the spiritual life. We must learn to wait.
The voice of the solar wind -- aptly named "chorus" -- is both ethereal and haunting. You can hear echoes of crickets and snatches of whole song in this celestial starry music that bathes our planet. Everything is in vibratory relationship with everything else.
From the "strings" to the fluctuating pulses of cosmic radiationb that attend the expansion of the universe, there is a song that sounds through the fabric of our physical universe. The music of life is heard everywhere. It is we who fail to hear the music.
