The Torah presents a story that concerns the patriarch Abraham entering into the land of Egypt. The Zohar reveals that Egypt is a code word pertaining to the depths of man's own negativity into which divine sparks of Light have fallen. The great spiritual leaders of history often descended into these negative regions to retrieve and elevate the sparks trapped within the dark recesses of our being.
It goes against the grain of man's nature to look inward and reflect upon his own amoral attributes. Our five senses are steadfastly tuned towards the external environment around us. The introspection and self-scrutiny performed by the sages, serves as a timeless repository of energy available to us through the letters and lessons contained herein. We acquire the inner strength to go deep into our self and expel the hardhearted qualities from our character.
