It is said that once John of Chrysostom* was walking along the seashore thinking over the question of the trinity and trying to reconcile it with finite reason; his attention was attracted to a boy sitting on the shore putting water into a cup. Approaching him, he said, "My child, what art thou doing?" "I am trying to put the sea into this cup," was the answer. "How foolish art thou," said John, "in trying to do the impossible." The child replied, "Thy work is stranger than mine, for thou art laboring to bring within the grasp of human intellect the conception of the trinity." (Abdu’l-Baha, Divine Philosophy, p. 152)
