Likutei Moharan 22:2/ליקוטי מוהר"ן כ״ב:ב׳

12. There is also a seal which is above this seal—corresponding to the hands which receive reproof from those who rebuke, as in (Job 37:7), “By the hand of every man is it sealed.” And the hands are synonymous with faith, through which reproof is received, as in (Numbers 17:5), “As God said, in the hand of Moshe, to him,” corresponding to (Exodus 17:12), “And his hands were faith.”

2Now, this seal needs extra safekeeping so that it should not be destroyed—so that the faith is not destroyed. For if, God forbid, the outer seal is damaged, it becomes possible for them to get close to the inner seal. They will break the inner seal by having damaged the outer seal, which is faith.

3And if, God forbid, this seal of the hands is damaged, heresy—the very opposite of faith—and mistaken beliefs <namely idolatry,> ensues. Principally, idolatry has no power other than what it receives from these hands, as in (Exodus 32:4), “He took [the rings] from their hand, and formed it [the gold] in a mold.”

4{As is explained in the Zohar (II, 192a) on this verse concerning the making of the Golden Calf: “What was is that made this action successful? It was because ‘[Aharon] took from their hands.’ If, when he took it from their hands, he had thrown it to the ground, then even if he had taken it afterwards, this terrible deed would not have been successful.” See there.}

5His rectification is also through the concept of hands, as in (Genesis 35:4), “They gave Yaakov all the idolatrous artifacts that were in their hands.”

6Chotem becomes nidat, as in (Isaiah 1:15), “Your hands are full of blood.” For YaD (a hand), when spelled out {as such: YOD DaLeT }, is numerically equivalent to NiDaT —namely idolatry, which makes impure as a menstruating woman (Shabbat 82a).
