303. Come and see: The first subject of the Torah we give to children is the Alphabet. This is a matter that mankind cannot comprehend, nor can it rise in their minds, not to mention saying it with their mouths. Even supernal angels and the most sublime cannot comprehend it, as these matters are the mysteries of the Holy Name. There are 14,050,000 worlds dependent upon the stroke of the Aleph א, MEANING THE STROKE OF THE UPPER YUD OF THE ALEPH, and 72 holy names are engraved in the impressed letters in them. The high and low beings; heaven, earth and the seat of glory of the King - are hanging from one side to the other side, MEANING FROM THE UPPER STROKE TO THE LOWER STROKE of the expansion of the Aleph. They sustain all the worlds and are the supports of the upper and lower beings within the secret of wisdom.
