Three Reasons for Concealing the Wisdom of Kabbalah

Not Necessary – No benefit will come from its revelation, and it can only confuse people. It should be remembered that all the destruction in the world results from engaging in trivial matters that are unnecessary.

Impossible – Because language does not have dominion to express anything of their properties due to their subtlety and spirituality. Therefore, any attempt to dress them in words can only mislead those studying them. Thus, to reveal matters such as these, permission from the Creator is required.
The explanation of matters in the wisdom of truth does not depend on the greatness or smallness of the Kabbalist, but it is a matter of the special illumination of the soul for this purpose.
If the soul of the Kabbalist comes from the surrounding light, students can understand it to the extent of similarity in form. Permission from above was given only to {Rashbi}, {the Ari}, and {Baal HaSulam} – therefore, we only study them.

The Secret of the Lord – Is revealed according to the degree of similarity in form with Him (the attribute of giving and love toward Him, blessed be He).
All practitioners of incantations and amulets, healers in the name of Kabbalah, and practitioners of “practical Kabbalah,” all mystics, and others who use the spoils of wisdom to derive material benefits must be distanced.

There is no detail or word in the wisdom of Kabbalah to which all three prohibitions do not simultaneously apply.

Condition for Revelation

However, one must ask, where did such a revelation of this wisdom come from? The answer is that the main burden lies solely on the third part, while the first two parts are not under a constant prohibition:

For from the “Not Necessary” part – it becomes “Necessary”,
and the “Impossible” – becomes “Possible”,
which happens for two reasons: either because of the development of the generation or by granting permission from the heavens, as happened to {Rashbi}, {the Ari}, and {Baal HaSulam}. And from these perspectives, all the true books composed in the wisdom emerge and are revealed.
Thus, the condition “I reveal a portion and conceal two portian (out of three)” is maintained and preserved.
