Kabbalah su Deuteronomio 22:7

18. [The beginner] must also know that it is not proper for a student [of Kabbalah] to inquire as to the essence of the three first [sefirot], which constitute intellect, wisdom, and understanding.¹In this enumeration, Keter is referred to as sekhel, i.e., “intellect.” It is furthermore improper to investigate the hidden force which created all that exists.²This is a reference to Keter and Eyn Sof. Since He, His will and wisdom and understanding are one, and they are true qualities of His essence, it is not proper to inquire [into it]. However, from Ḥesed and Gevurah and below, there is no sin in investigating them, for they are qualities which have been emanated in order to direct the lower beings. One who increases his investigation into them is called industrious and will be rewarded. Similar to this [case] is that which is written, You shall surely send forth the mother—which is Binah³Binah, linked with Ḥokhmah, is the “mother” of all the lower sefirot.— and the sons⁴The seven lower sefirot. you will take for yourself (Deut. 22:7), to inquire and investigate. Thus also, inquire now as to the first days (Deut. 4:32).
