―From the praise and song of each day, ―From the jubilation and exaltation of each hour, ―And from the utterance which preceedeth out of the mouths of the holy ones ―And from the melody which welleth up out of the mouths of the servants ―Mountains of fire and hills of flame ―Are piled up and hidden and poured out each day.
Prayers That Create Fiery Crowns in Heaven
