You must not think of the light of the sun as the true Light of God. It is a reflection of the true Light. That other Light, that we can neither know nor comprehend, is so subtle, so highly potent that, for us . . . it is darkness.
Every moment in life is a prayer, or could be. I think you can pray yourself into the mystery of the moment, or allow for the blessings of the moment to sustain you. Every moment is an invitation, and whatever you do in that moment, if it's dedicated to God, then it is a prayer.
