Likutei Moharan 21:4/ליקוטי מוהר"ן כ״א:ד׳

14. Now, this sukkah /spirit of holiness/Godly influx is synonymous with the concept of makifin (encircling, transcendent). For this intellect is so very great that the mind is incapable of holding it. It does not enter the mind, but encircles <it from without>. In a similar sense, we see that there are a number of profound disciplines which the human mind is incapable of understanding clearly; such as the numerous paradoxes which perplex us, e. g. foreknowledge and free will. The human mind is incapable of understanding this principle.

2And this intellect is synonymous with the concept of encircling. It does not enter within the mind. Rather, it surrounds it from without, and the inner intellect receives its vitality from this transcendent intellect.

3And know! <principally, the power of free choice exists> as long as the intellect is not so great that it can understand foreknowledge and free will. Then the power of free choice is as it should be, for one has the power to choose life or its opposite.

4But when this transcendent intellect is <internalized in the mind> and the intellect then expands and reveals to man the [understanding of] foreknowledge and free will—then free will will be nullified. Because then, by virtue of an expansion of the intellect, he leaves the category of human and ascends to the category of angel. And then, free will is nullified. <Hence, this is> the essence of the power of free choice: <[it exists] as long as it remains unknown, as explained>.

5And this is what our Sages said (Berakhot 17a): “In the future, the tzaddikim will sit with their atarot (crowns) in their heads, [delighting in the radiance of the Shekhinah].”

6It should have said “on their heads.” <However, this was their intention,> because in the future free choice will be nullified. Thus, “the tzaddikim will sit.” “Sitting” indicates an absence of free choice, as in (Psalms 2:4), “He Who sits in heaven,” which indicates an absence of change. This is because motion indicates a change from one will to another, whereas sitting points to an absence of change—namely, the nullification of free choice.

7And this is due to “their ATaRot (crowns).” This alludes to the aspect of encircling, as in (1 Samuel 23:26), “Shaul and his men OTRim (encircled) David.” “In their heads” and not “on their heads.” In other words, the transcendent intellects will be internalized in the mind. And then, all the profundities which <they were> incapable of understanding will be internalized, in the inner mind, and <they> will know and comprehend them. They will <truly> emerge from the category of man and <enter> the category of angel, and free choice will be nullified.
