Likutei Moharan 30:5/ליקוטי מוהר"ן ל׳:ה׳

15. One who possesses this wisdom must see to draw life-force into it; giving vitality to this lower wisdom, each person commensurate with the lower wisdom that he possesses <and> in accordance with the lower wisdom that is in each world.

2And the main life-force comes from the Light of the Face, as in (Proverbs 16:15), “In the light of the Living King’s countenance.” One therefore has to elevate Malkhut, lower wisdom, to the Light of the Face, which radiates on the Three Festivals.

3This is because the essence of the Light of the Face is joy, as is written (Proverbs 15:13), “A joyous heart makes a good countenance”; and the essence of joy is from the mitzvot, as in (Psalms 19:9), “The instructions of God are upright, they make the heart rejoice.” And the main joy is in the heart, as is written (ibid. 4:8), “You placed joy in my heart,” with the heart of the entire year being the Three Festivals. This is as in (Leviticus 23:4), “Eileh Moadei YHVH —These are the festivals of God.” The first letters spell EMY (my mother), which is “EM to binah (understanding)” (Proverbs 2:3). And understanding <is the> heart (Tikkuney Zohar, Introduction).

4Now, the joy of all the mitzvot which we fulfill throughout the year gathers in the heart, the Three Festivals. This is why they are days of joy, as in (Deuteronomy 16:14), “you will rejoice on your festivals.” Then the face radiates because of the joy, as in, “A joyous heart makes a good countenance.” Because of this, we were commanded (ibid. 16:16), “Three times each year, all your males shall thus appear before the countenance of God your Lord”—in order to receive <from the Light> of the Face.

5This is the meaning of: A man is obligated to receive the countenance of his master on the festival (Sukkah 27b). <That is,> in order to receive <from the Light> of the Face, to give vitality to the aspect of Malkhut. { “Righteousness will go to His face and set his p’amav (st eps) on the way” (Psalms 85:14). }

6And this is the meaning of: “Righteousness will go to His face.” “Righteousness” <is the> Malkhut of Holiness when it is led to the Light of the Face. This primarily happens in the aspect of “set his P’AMav on the way”—i.e., three P’AMim (times) each year through which one receives from the Light of the Face, as explained.

7And this is, “The upright will dwell in Your face” (Psalms 140:14). “Upright” alludes to “The instructions of God are upright, they make the heart rejoice.” They compose, cause to radiate and organize the Light of the Face, as above.
