Likutei Moharan 66:7/ליקוטי מוהר"ן ס״ו:ז׳

17. And this is the deeper meaning of: There was once a righteous man whose wife sought to provoke a fight. He left and spent the night [in the cemetery], where he overheard two spirits engaging in conversation (Berakhot 18b). As the Talmud there brings, their conversation was about livelihood. “Provoke a fight” is the aspect of wrath; “two spirits” corresponds to the abovementioned two spirits produced by mitigating wrath—i.e., when potential is turned into actual, as explained above. This is contingent on the aspect of livelihood, through which we turn potential into actual.

2[The Rebbe] did not reveal any more about how this entire lesson is hinted at in this Talmudic passage.
