The fourteenth card of the Tarot is called Temperance (or Balance). This card portrays an angel holding a pitcher in either hand. From the pitcher in his left hand he is pouring liquid into the one in his right hand. What is this liquid the angel is busy pouring? This liquid represents life, the flow of divine life. If he were to interrupt the flow, there would be no more exchange, and life would stop. As for the angel, he represents us. Yes, each one of us is the angel that has the power to work with the two pitchers. Whether or not the divine world, the spirit, comes from on high to animate, exalt, and vivify matter below depends entirely on us.
It is this descent that we are preparing when we strive to rise through prayer and meditation, for the downward movement can only happen if it is preceded by an upward movement. The spirit can descend only if we strive to rise, that is to say, if we do the preliminary work that enables the spirit to manifest through us.
