Likutei Moharan 169:2/ליקוטי מוהר"ן קס״ט:ב׳

12. Now, the way to mitigate judgment is by a person judging himself. That is, in whatever he does, he himself should judge and evaluate himself in every aspect: was that the appropriate way for him to behave? He should search his ways and properly rectify them, according to the judgment and law of the Torah.

2Through this that a person judges and evaluates himself, he mitigates and eliminates the judgment Above. For when there is judgment below, there is no judgment Above (Devarim Rabbah 5:4).

3Then, when the judgment is mitigated, the blood departs from the feet, in which case the joy is able to extend to the feet until one merits to dance.
