SEPHER YETZIRAH OR THE BOOK OF CREATION

The "Sepher Yetzirah," or "The Book of Formation," is a philosophical treatise exploring the origins of the universe and humanity through the unique interplay of Hebrew letters and numbers. It delves into Kabalistic principles and contrasts with the "Zohar," focusing on the Microcosm and the universe. The work is attributed to Abraham, who challenged contemporary beliefs.
