This is for those who are interested in learning about the Hebrew letters:
The Hebrew Alphabet:
"Judaism has always regarded Hebrew as a sacred language, the medium of divine communication. For millennia, the sages and mystics have taught that the letters are no ordinary expression. The very word for "letter" in Hebrew--Ot--means sign or wonder; that is, a heavenly revelation. The more we learn about the letters through both study and meditation, the greater becomes our inner development". Edward Hoffman
The 22 Letters, And No Vowels
The Hebrew language is comprised of 22 letters, five of which are known as double (or mother letters, as they have two distinct forms: when beginning a word and when placed at its ending). These letters are Kaf, Mem, Nun, Pei, and Tzadi. They were originally known only to the righteous such as Abraham, and later, to Moses, Joshua, and the Seventy Elders of Israel under their leadership. They brought the knowledge of these special Hebrew letters to the Holy Land, where through the Prophets, the entire Jewish people came to use them.
The Hebrew language originally contained no vowels, though the Ayin or Aleph were sometimes utilized for that purpose. Vowel signs were developed during the second half of the first one-thousand years.
Dating back to Talmudic times, the Hebrew letters have not only been celebrated as holy, but also venerated as an actual tool for spiritual mastery. Traditionally, the two most preferred techniques have been gematriyah and notarikon. In gematriyah, words with dissimilar meanings but equal numerical values (since each Hebrew letter also has a number associated with it) are probed for their hidden linkages.
In notarikon, words are broken down into sentences composed of initial letters. Thus, the first word of the Ten Commandments, ANoKhY ("I Am") alludes to the sentence Ario Nafshoy Katovit Yahovit ("I have written and given myself to you in this book").
