Once, lying awake, he repeated His name, and as he thus thought about Him he sought some sign of that One who is really worthy of worship. Again, in his visions he saw the star, and arose to ask, "Art Thou the God?" And the answer came from within, "It is not He. It comes and goes, for it is not stable nor steady. An object that is worthy of worship must be constantly before one." Then, next day, he saw the moon and asked, "Art Thou the God?" And the answer came, "No, for the moon takes its light from the sun." Then he saw the sun and asked the same question, and the answer came, "No, that which appears or disappears, however perfect in its light and form, cannot be the eternal God."
