As you recall your father by his photograph, so likewise the worship of the image reveals in a flash the nature of Reality. Do you know what God with form is like? Like bubbles rising on an expanse of water, various divine forms are seen to rise out of the Great akasa of Consciousness. The Incarnation of God is one of these forms. The Primal Energy sports, as it were, through the activities of a Divine Incarnation.
