Likutei Moharan 35:5/ליקוטי מוהר"ן ל״ה:ה׳

15. Now, the main mentalities, which we receive by means of faith, are received only from the Light of the Face, as is written (Proverbs 16:15), “In the light of the King’s countenance there is life.” “Life” is the mentalities, as in, “Wisdom gives life.” They receive from the Light of the Face by way of faith, which is called Malkhut. This is the aspect of Yerushalayim, as is written (Genesis 14:18), “And Malkitzedek, king of Shalem”—which Onkelos renders: king of Yerushalem.

2And [Yerushalayim] is an aspect of faith, as is written (Isaiah 1:26), “city of righteousness, faithful city.” And it is an aspect of night, as in, “Your faithfulness in the nights.” It is also an aspect of the Torah’s plain meaning, as in, “He has made me dwell in darkness,” and as in, “and the darkness He called Night.” And it is an aspect of the small light, as is written (Ecclesiastes 9:14), “There was a small city”; and as in (Genesis 1:16), “and the small light to rule the night.”

3And there are a number of aspects to the Light of the Face. There are those who receive the intellect from the Light of the Face of the Torah. For the Torah has seventy faces. And there are those who receive from the Light of the Face of the tzaddikim. When the tzaddik is kindly disposed toward him, then he receives a new intellect and a new soul. This is because the essence of the intellect comes from the Light of the Face, as is written (Ecclesiastes 8:1), “A man’s wisdom [is from] the light of his countenance.”
