According to a Talmudic legend, an angel escorts the soul from its abode in heaven into the tomb and there unites it to the embryo. The angel tutors the new being in the mysteries of the world, transporting it to heaven and darkness to see the heights and depths of creation, revealing to it the ways of beauty, truth, and goodness, disclosing the potential of its future life on earth, even to the time and place of death. As the child matures within the womb, it ponders the wonders it has seen. Then, at the instant of birth, the angel touches the child on the mouth, erasing all memory of these marvelous revelations.
What is one to do with such moments, such memories, but cherish them? Who knows what is beyond the known? And if you think that any day the secret of light might come, would you not keep the house of your mind ready? Would you not cleanse your study of all that is cheap, or trivial? Would you not live in continual hope, and pleasure, and excitement?
