Likutei Moharan 102:1/ליקוטי מוהר"ן ק״ב:א׳

1“You shall be in charge of my court, and by your mouth shall all my people be supervised; [by the throne alone shall I be greater than you].” (Genesis 41:40)

2The matter is as follows: All that the Holy Blessed One created, He created solely for the sake of His glory (Avot 6:1)—in order to reveal His Malkhut. This causes the forces of evil to be subdued under the Divine Presence.

3By what means is His Malkhut revealed? When [God] provides Israel with abundant good, <the nations of the world> then acknowledge that “His Malkhut rules over all” (Psalms 103:19). And what enables us to draw this influx of bounty? Prayers. This is because <the mouth and> the letters are vessels for receiving the influx.

4Therefore, every person has to be vigilant when praying; he should pray in such a way that can arouse the flow of bounty into the world. As our Rabbis, of blessed memory, taught: Every person must say, “The world was created for my sake” (Sanhedrin 37a).

5And by what means is it possible to arouse the flow of bounty into the world? Through fear. As our Rabbis, of blessed memory, taught: Anyone who has in him the fear of Heaven, his words are heard (Berakhot 6b).

6Now, there are two types of fear. The first is the higher fear that comes over a person upon occasion, when it <itself> chooses to. For this kind of fear <one receives> no reward. And there is a fear that comes by virtue of one’s own effort. This fear is referred to as “The tzaddik rules with the fear of God” (2 Samuel 23:3). With fear such as this, prayer is heard. An influx of bounty thus descends to the world, and His Malkhut is revealed.
