Prayer is zivug (coupling) with the Shechinah. 1 Just as there is motion at the beginning of coupling, so, too, one must move (sway) at the beginning of prayer. Thereafter one can stand still, without motion, attached to the Shechinah with great deveikut. 2

As a result of your swaying, you can attain great bestirment. For you think to yourself: “Why do I move myself? Presumably it is because the Shechinah surely stands before me.” This will effect in you a state of great hitlahavut (enthusiasm; rapture).
