The '1st of Tishrei' on the Hebrew calendar is the sixth day of Creation. It is the day Adam and Eve were brought into the world, the day the flood waters subsided for Noah, the day of Isaac's binding on the altar, the day Abraham's wife Sarah (who suggested and rejected Ishmael's mother) died, the final day of Israel's conception and the day Israel was judged at Mount Sinai and found worthy to receive the Torah.
['In the beginning'] B'reishit - בראשית is the first word of Torah, its letters also spell,א בתשרי - (Alef b' Tishrei) the '1st of Tishrei'.
The consistently stated Messianic objective of Judaism, Christianity and Islam is to ready the world (humanity) as an appropriate HOME for G-d to dwell. Moses, a recognized prophet of the Quran, wrote the Torah (The Bible). It tells that the Messiah will come through the nation of Israel. It is this that President Mahmood Ahmadinejad pleads against in the opening statements of his blog (see Being Holy Blog 8/13).
The first letter of Torah is the letter ב - 'beit' (written בית) is equal to the number 2 (all Hebrew letters have a numeric value). 'Home' is also written בית, but pronounced 'BaYiT'. If we remove the letter (beit) ב from the first word (B'reishit) then ראשית (reishit) [beginning] has a numerical value = 400+10+300+1+200 = 911. Adding, 911+2 for (beit) ב, restores B'reishit -בראשית [in the beginning] = 913. 'Reishit' represents supernal Wisdom. Perhaps Osama's desire of it diverted the angel of death to strike on that fateful 9/11 day.
The extended numerical value of בית (bayit or beit) = 412, also = תאוה (ta'avah) meaning 'desire' or passion. Generally considered negative, desire's association with holiness takes on a positive meaning signaling that supernal desire will bring the presence of G-d into the home we make.
There are many ancient esoteric teachings associated with the letter ב (beit), particularly as they relate to the rebuilding of the third and final temple in Jerusalem at the time of the Messiah. These teachings have been circulated in Israel and greater Arabia for thousands of years.
So, what does Osama's missing ב (beit) mean for the world and its' Messiah?
Modern academic analysts of the Bible discredit its authorship to a time much later than Moses. Almost all of these theories make the point by inference. In our scientifically focused world some think it preposterous that G-d could have written or dictated this document! With this fixed mindset our modern literary archaeologists relegate the writing of Torah to four men or groups who contributed to it over a span of several hundred years. Their analysis disregards the critical cultural importance of this text to the Jews that embrace and maintain it as the essence of life.
It is rare to find even one critic of Bible who has also studied the complete traditional works of Torah including its inner meanings (Kabbalah), before reaching their published, often ignorant conclusions. Without the dimension of commentary it is impossible to conclude leaving their narrow analysis a flawed methodology.
Kabbalah's esoteric reputation quickly aligns with modern knowledge of technology, science and our enlightened understanding of nature. The logic of Kabbalah permeates every aspect of the spiritual and physical world, connecting all the dots, whilst its purpose enables students to grasp, actualize and experience the concept of a Creator and the presence of G-d. Torah (Bible) is considered by its observers to have been transcribed by G-d's prophet Moses at Mt. Sinai. It is the oldest, most complete and comprehensive Holy work in existence; if we need proof, some Dead Sea Scrolls, are a completely intact 2300 year old body of Torah.
Kabbalah scholars studying Torah (Old Testament) rely on methods, which have been used since ancient times, to reveal esoteric knowledge and ancient wisdom concealed by our limited interpretation of its holy words and letters. Unlike other languages, all Hebrew letters perform a grammatical and a numerical function and the mystical nature of each letter is said to reflect in its unique form representing Godly energy. When letters are assembled into a word, the inner meanings contained in the word are concealed. As such, an accurate understanding of each letter reveals details of the word and therefore the inner spiritual or physical construct of the object or subject that the word describes[1].
When Torah is studied from this point of view it can be emotionally and intellectually overwhelming, as such Kabbalah was concealed for 1200 years following the destruction of the Second Temple in Jerusalem. Today many users of the Internet busily translate and publish accurate Kabbalah all the while revealing its indisputable logic to a growing audience. This rapid growth in popularity and access is the fear of fundamental Islam, this 'spreading light' is driving their dark desire to destroy, to turn back time and to stop Torah from defining The Home. This is the reason they are fearful and intent on destroying Israel and its friends.
Its not surprising to learn that Ishmael (Abraham's son through his servant Hagar), representing 'Iran' and friends, married his daughter to Jacob's (Israel's) twin brother Esau, representing 'Rome' and friends and that, according to the 'end of days' prophecy (some 45 years from 5761/2001), these two will join against Israel. So, we should not be surprised to witness the United Nations joining with Iranian and Syrian interests in Lebanon to pursue Israel and when this occurs we will know that the Messiah of life is here and the 'end of days' are near for the dark days of terror.
The following details will help you contemplate the depth of Kabbalah's logic.
'Gematria' is the study of relationships between Hebrew words and phrases included in Torah. This vast and complex study, considering the sheer volume of letters included in Torah, has revealed deeply esoteric concepts hidden within its pages and its study continues to produce inspiring results.
Interestingly, the Hebrew word for 'letter'; אות (ot)[2] also means a 'sign' or 'wonder' and is the root of the Hebrew word meaning 'to reveal'.
By example; a Gematria rule from The Principle of Letter Pairs, known as 'Atbash' is discovered by mirroring and reversing the sequence of letters in the Hebrew alphabet. This concept is derived from the moment of creation when the Heavens were folded. This practice, originating in knowledge derived from the early portions of the book of Genesis, is used to reveal inner meanings. Further, the ordering of Hebrew's 22 letters (representing energy forms) occurred in the period prior to creation. In order to obtain deeper insight, the reverse order of letters can be applied to a word to reveal its 'word energy' as it existed prior to creation. The letters (in their reverse order) form a new corresponding word which was previously concealed and from which new information is revealed.

These are the 3 Mother letters representing the primary energies associated with creation including the process known as thesis, antithesis and synthesis.

These are the 12 Elemental letters representing the 12 diagonal energies around which much of our universal existence is based including months of the year.
These are the 7 Double letters around which energies are said to ascend and descend in a vertical direction and upon which most of our earthly presence is affected including days of the week.
