The letters by Rav Hamnuna Saba
Synopsis
Individual energy forces, which express themselves as Hebrew letters, came before the Creator requesting that they be the instruments by which the world is created. The Creator eventually agreed to utilize the letter Bet ב, as this particular letter begins the Hebrew word Brachah [Blessing]. The Zohar then depicts the unique attributes of each of the twenty-two letters and the spiritual energy they emit. All these forces and their power of blessing are transferred to us when we visually scan the Aramaic text and learn the lessons it holds.
