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.
In the beginning of every silent meditative period, we send forth a glad call to the Eternal. It is so good to be able to go Home, even for a few moments! As our thoughts calmly turn from the outer to the inner world, we soar into communion with a joyful salutation addressing the Eternal as though standing on a high cliff with arms outflung to the heavens. By degrees we are included in the silence of the Infinite.
