Likutei Moharan 5:7/ליקוטי מוהר"ן ה׳:ז׳

17. This is the explanation [of the opening verse]: {“With trumpets and the sound of the shofar shout out before God, the King. Let the sea thunder and all within it, the tevel (world) and all its inhabitants. Let the rivers clap their hands, the mountains y’ranainu (sing joyously) together. At the presence of God, for He is coming to judge the earth” (Psalms 98:6-9).}

2With trumpets and the sound of the shofar — That is, by means of the voice that is released [during prayer]

3Let the sea thunder — thunder is generated. This corresponds to “The sound of Your thunder was in the sphere.”

4the tevel and all its inhabitants — This alludes to the heart and its arteries. “Thunder was only created….”

5TeVeL is made up of the letters Tav LeV. TaV connotes a mark, as is written (Ezekiel 9:4), “and hitvita TaV (inscribe a mark).” The voice is imprinted on the heart, as in, “Thunder was only created to straighten [the crookedness of the LeV].” And because of this:

6Let the rivers clap their hands — This alludes to joy, as mentioned above: “and joy for the straight of heart.” And by means of this joy…

7the mountains y’RaNainu together — RiNah connotes prayer, as is written (1 Kings 8:28), “Hearken to the rinah and to the prayer.”

8mountains — This alludes to tzaddikim. By means of the heart’s joy they are able to pray, and once they realize that the judgment has already been decreed, they disguise their prayer in a maamar. This is the explanation of < mountains> together —[the tzaddikim] disguise their prayers together with stories.
