ABSTRACTIn Freemasonry, there is often talk of the golden ratio: what does it represent and why is it important? Freemasonry uses numbers in a symbolist approach: what is the connection with the Divine? Can the Zohar shed light on this subject?In Freemasonry, alchemical and esoteric traces can be detected in symbolic form. Kabbalah and numerology seem to be closely linked and present in Masonic symbolism. Can reading the Zohar enlighten us? These are important questions for the initiated, but also for the uninitiated who are interested in symbolism and esotericism.
