The perfect Saint makes the divine revelation of the nourishing light flow. The saviour, the Saint, makes the divine revelation of the water flowing sound flow and unites the devotee with the Desirable (God). The living Saint makes the divine revelations flow and guides the devotee to worship God. The Saint gives the devotee divine food and controls him with the audible sound-current.
