When one behaves in a negative manner, he immediately disconnects himself from the Light of the Creator. Moreover, negative deeds also block and prevent an individual from receiving any spiritual Light from the righteous souls who are in this world to share their Light with all mankind.
Every act of negative behavior can be likened to draping a layer of cloth over a lamp. Life grows progressively darker. We remove these veils from ourselves through the letters and lessons of this section so that we may receive all the Light that is ever-present from the devout souls who dwell among us in our generation.
