With the models we have found in B'Reshit, Sefer Yetzira becomes unambiguously readable and its meaning becomes clear. This is considered an outrageous idea mostly because neither academic nor religious scholars have any real appreciation for mathematics. Persons whose expertise is in bible studies or paleography or archeology, etc., are usually interested in words, not in mathematical abstraction. Worse, yet, I have found to my shock and surprise that most persons who learn by words actually believe that that is the only possible way to learn. Well, yes and no.
Spiritual experience is ineffable.
Ergo, record the exercise and not the discussion. These ideas seem to offend everyone. Unfortunately reality sometimes demands that we look where we are uncomfortable if we are going to rise above the banal and gain new understanding. In my opinion it is about time that both the academic and religious scholars of Judaism took the teachings of Judaism seriously. When we are taught that the letters are holy and elements of creation, we should not dismiss this as the confabulation of religious wishful thinking or mythology.
