to find that you ,would have to read this booklet; method that is being used to determine one system of messaging is called ELS or equdistant letter sequence or skipping of equal intervals of letters.by this method the entire 304,805 letters of Torah were written in 10 x 10 grids which is a common practice in cryptanalysis to facilitate the identification of skipped-letter sequences.
by this method the word Torah is repeatedly found in precise 49 letter sequences , tetragramaton in 7 letter sequences almost like a hidden signature.The probability of this being a coincidencehas been estimated at about one in three million. this method is not a new , it is been used in 13 century. Rabbi Moses Cordevaro said :"The secrets of the Torah are revealed in the skipping of the letters."
please remember that I am only just reading this and yes I find it fascinating, the same as I find sunset,changes of season and others marvels of nature fascinating. I did not wrote the book so i am not going to defend every single tought. Is this book going to give me all the ultimate answers? - no. Is this information presented to change your mind? - i would not even dream about it.
it is simple one sign on my spiritual path that I wanted to share
