Feast of the Transfiguration:  the ‘uncreated’ light of God which shone at the Transfiguration is the same light that is sought by hesychasts, those Orthodox monks and others who seek the ‘prayer of the heart’ and inner union with God.  Like all of God’s blessings, it has one purpose:  to fill our souls and draw us closer to the Lord.
