There is a strict condition during the engagement in this wisdom: to not materialize the matters with imaginary and corporeal issues…. To rescue the readers from any materialization, I composed the book Talmud Eser Sefirot (The Study of the Ten Sefirot) by the Ari, in which I collected his major explanations and presented them in a simple and easy language.

Most students materialized the matters explained in Kabbalistic books and although the spiritual concepts are above time and above place, pictured them as set in times and places. Additionally, they were confused by the fact material is expressed in corporeal terms.
Thus, I have come out with this preface, to connect the matters and the foundations of the wisdom in a concise manner, so it will be readily available to those who want to study this science.
