Likutei Moharan 250:5/ליקוטי מוהר"ן ר״נ:ה׳

15. This is the explanation of what the necromancer answered Rav Ketina: What is an earthquake? At the time the Holy One remembers His children, that they are living in suffering among the <nations>, He sheds two tears into the Great Sea, and His voice is heard from one end of the world to the other (Berakhot 59a).

2That is, when the Holy One recalls that they are living in suffering among the <nations>—specifically among the <nations>, for this is the crux of the suffering, that they reside among the <nations> and have learned from them, so that they have fallen from daat and attribute <everything to nature and fate>. This is the essence of their suffering, as explained above.

3And this is “He sheds [two] tears…”—i.e., He infuses them with Providence. For tears are the aspect of Providence, as our Sages, of blessed memory, said concerning the verse “The clouds return after the rain” (Ecclesiastes 12:2)—this is the vision, which is diminished after crying (Shabbat 151b). Thus it is that tears take away a portion of the vision, and the vision is drawn into them. Hence the tears are elements of Providence and vision, because tears take away the vision, as explained above.

4This is: He sheds two tears—He draws the elements of Providence.

5into the Great Sea—This is the aspect of the <nations> that rule over the Jews, the aspect of “but the wicked are like the troubled sea” (Isaiah 57:20). This then produces the aspect of greatness/Providence, the aspect of prayer, which is great, as explained above. And this is:

6His voice is heard from one end of the world to the other—That is, He draws Providence from “one end of the world,” from the Final End, “to the other end”—to put an end to the <nation that rules over them>, corresponding to “The end… the end is coming,” as explained above.
