Likutei Moharan, Part II 72:7/ליקוטי מוהר"ן·תנינא ע״ב:ז׳

17 . However, this leader must be a great ascetic, with great holiness, since only then is he able to be a leader of the Jewish people. For it is his great abstinence and holiness which enables him to see and gaze at every Jew and apportion greatness to each one merely by gazing at him, as in “As for you, you shall see,” as mentioned above. For this gazing is dependent upon holiness and great abstinence. Therefore, Moshe Rabbeinu, who was holy, and exceedingly abstinent by Divine fiat, as it is written (Deuteronomy 5:28), “As for you, you shall remain here with Me,” was able to see and gaze at Israel and apportion greatness to them through this.

2And this is the meaning of “As for you, you shall see.” Specifically “you,” since only Moshe, who was a very great ascetic, with great holiness, merits this [power of] gazing. For this gazing, the concept of “As for you, you shall see (techezeh),” depends solely on holiness and abstinence from this desire.

3This is the concept of “and they washed HaZoNoT (the harlots)” (1 Kings 22:38)—and our Sages, of blessed memory, expounded: to clarify two CheZyoNoT (visions) (Sanhedrin 39b). That is, to the extent that a person washes himself of this desire, the concept of “and they washed hazonot”—i.e., they washed themselves of this desire—he likewise clarifies and burnishes two chezyonot: the concepts of “As for you, techezeh,” [and] “Chazita (If you see) a man quick in his work…”—i.e., the aforementioned concept of gazing. For the aforementioned gazing primarily comes about through holiness and abstinence from this desire. This is because this desire is a blemish of the eyes, as it is written (Numbers 15:39), “You shall not stray… or after your eyes, after which you go whoring.”

4Therefore, [a true leader] must sanctify himself to a very high degree, with great abstinence from this desire, as then he will have the pure eyes with which to see and gaze and to apportion appropriate greatness to each one merely by gazing at him, as mentioned above. And specifically then he will be able to be a leader of the Jewish people, as mentioned above.

5But when the Jews lack such a leader and guide, everyone is genuinely mixed up and confused. Whoever wants notoriety takes it, as is presently the case on account of our numerous transgressions. For the Jewish people must have a guide to supervise and ensure that each one has the standing genuinely appropriate for him. And this guide must be an ascetic and very holy, analogous to the holiness and abstinence of Moshe. He will then be able to lead the Jews and, merely by gazing, give each one the greatness appropriate for him, as mentioned above.
