Likutei Moharan 21:2/ליקוטי מוהר"ן כ״א:ב׳

12. But to arrive at this concept of Godly influx is impossible, unless one sanctifies his mouth, nose, eyes and ears. Precisely these are what radiate the Godly influx to him.

2In other words, a person should guard himself from allowing anything false to emerge from his mouth. <With this, he sanctifies his mouth.> And he should have fear of Heaven. <With this, he sanctifies the nose,> as in (Isaiah 11:3), “He shall breathe of the fear of God.” And he should have faith in the sages. <With this, he sanctifies the ears,> as in (Proverbs 22:17), “Hear the words of the wise.” And he should keep his eyes shut so as not to look at evil. <With this, he sanctifies his eyes.>

3For precisely these are what arouse the Godly influx to come. This is because the mouth and the nose and the eyes and the ears are contingent upon the mind. They waken the mind that it should be in the category of “front,” in the category of face.

4This is the concept of (Psalms 119:160), “Rosh devarkha (Your very first utterance) is truth”—the aspect of mind as it applies to the mouth. And this is (ibid. 111:10), “Reishit chokhmah (The beginning of wisdom) is the fear of God”—the aspect of mind as it applies to the nose. And this is the concept of (Proverbs 9:8), “Rebuke the wise man and he will love you”—the aspect of mind as it applies to the ears, as in, “Hear the words of the wise.” And this is the concept of (Genesis 3:7), “And the eyes of both of them were opened”—the aspect of mind as it applied to the eyes.

5And precisely these are the “seven candles.” For the mouth, the two nostrils, the two eyes, and the two ears correspond to the seven candles. The menorah is the head—the mind. And the face of the menorah is the Godly influx.
