Likutei Moharan 44:6/ליקוטי מוהר"ן מ״ד:ו׳

16. “Prayers were established to parallel the tmidin (regular-offerings)”—i.e., an aspect of the Land of Israel. In other words, by clapping the idolatrous thoughts are eliminated. This is because: Whoever lives in the Diaspora is like someone who has no God; but whoever lives in the Land of Israel is like someone who has a God. Thus by clapping, he lives in the air of the Land of Israel and has a God, and so the idolatrous thoughts are eliminated.

2And prayer is an aspect of faith, as is written (Exodus 17:12), “his hands were faithful until the sun set.” Onkelos renders this as: “[his hands] were spread out in prayer.” But opposing faith are the heresies of the idolatrous thoughts. Their rectification is through tmidin —through the Land of Israel, through clapping.

3This is the explanation of “You will be a crown of tiferet (beauty) in the hand of God” (Isaiah 62:3). The explanation is: Through “the hand of God”—through clapping, which rouses the hands of the Holy One, as above—<you rectify> idolatrous thoughts. This is because through idolatry he blemishes Tiferet (Beauty), as is written (ibid. 44:13), “like the tiferet of man, to sit in a shrine.” [But] by rectifying one’s thoughts, “a crown of tiferet” is made—<the aspect of> Tiferet is crowned by “the crown with which his mother crowned him” (Song of Songs 3:11). <A word to the wise is sufficient.>
