Likutei Moharan 21:3/ליקוטי מוהר"ן כ״א:ג׳

13. Now, this Godly influx is synonymous with the sukkah. This is because SuKkAH corresponds to “SaKhAH (she foresaw) with the spirit of holiness.”

2For the spirit of holiness is the Godly influx. And this sukkah comes about through the “seven clouds,” which correspond to the seven candles. Through them, a person attains the face of the menorah—the sukkah /Godly influx. The spirit of holiness is so called because of the wisdom; it being the spirit of wisdom which comes from holiness, as is known.

3And this is the meaning of what our Sages said (Sukkah 11b): “From where do we know that one is permitted to cover the sukkah only with something that cannot be made impure and which grows from the earth? It is written (Genesis 2:6), ‘A mist rose from the earth’—just as a mist cannot be made impure and it issues only from the earth….” The mist is the above mentioned clouds. They are synonymous with holiness.

4And which grows from the earth. For this would be receiver must be a sage, as the Holy One “gives wisdom to the wise” (Daniel 2:21), as in, “I have placed wisdom in the heart of all those who are wise of heart” (Exodus 31:6).
