Likutei Moharan 34:8/ליקוטי מוהר"ן ל״ד:ח׳

18 . Consequently, each person has to engage in private conversation with His Maker so that the nekudah —the aspect of “My mouth utters wisdom”/<the yod>—shines into the <heart>—the aspect of “and the meditations of my heart are understanding”/<the vav>. And through this <the disgrace/evil loves>/foreskin of the heart is eliminated.

2And each person also has to talk to his friend about the fear of God, so that his heart receives inspiration from the nekudah in which his friend surpasses him, as in, “And one received from the other.” For this aspect in which his friend surpasses him is an aspect of a nekudah. There, in this nekudah, the love, which is called “priest,” resides. This nekudah is an aspect of tzaddik with regard to his friend, and this nekudah shines into his friend’s heart, which is called vav.

3Now, all these nekudot —i.e., the nekudah that is called “My mouth utters wisdom” and also the nekudah that each person has which his friend does not—are extensions of the tzaddik. For he is the encompassing nekudah of all Israel. Everyone first has to receive from the tzaddik, and afterwards they will receive from each other. And each person will receive from within himself, <by engaging in private conversation with His Maker>. And through these three < nekudot> the disgrace/foreskin of the heart/evil loves is eliminated. This is: “love covers up all faults,” because that is where holy love resides.

4And this is: When Yosef the tzaddik was born, Rachel said, “The Lord has gathered away my disgrace” (Genesis 30:23). For when the nekudah in which holy love <resides> is revealed, then the disgrace/foreskin of the heart/evil loves is eliminated.

5This is also what is written in connection to Yosef: “that my own mouth is speaking to you” (Genesis 45:12). Rashi explains: “As my mouth is, so is my heart.” In other words, he shone his nekudah into his vav; he shone “My mouth utters wisdom” into “and the meditations of my heart are understanding.” And it is written of him (Genesis 50:21), “and he spoke to their hearts,” which Rashi explains: words that calm the heart. That is, he shone his encompassing nekudah into all <their> hearts.

6Thus it is that as a result of these three nekudot [the heart is inspired]. That is, [through] the binding to the tzaddikim and their shining into him, because they are the encompassing nekudah, they inspire his heart; and through speaking with his friend, each person is also able to shine into and inspire his friend’s heart; and through himself, by engaging in private conversation with His Maker <in hitbodedut>, he can also inspire his own heart by means of “My mouth utters wisdom” and so remove the foreskin of the heart, <the evil loves,> from himself.
