Likutei Moharan 77:1/ליקוטי מוהר"ן ע״ז:א׳

1“Vehayah Hashem Lemelekh (Then God will be King) over the entire earth.” (Zechariah 14:9)

2Behold, as a rule, everything that we do—be it prayer or study Torah—is with the aim of revealing the Malkhut (Kingship) of God.

3For the breath is the aspect of the letter Heh, and the drawing out of the voice is the aspect of the letter Vav. When one studies and prays with fear and love, the aspect of Yod-Heh is revealed (Tikkuney Zohar # 10, p.25b) .

4A person who studies one law in this manner creates a single world. When he studies the entire tractate, the Matronita (Mistress) is made [whole]. And the laws are Her worlds (Tikkuney Zohar, Introduction, p.14b), because there is no king unless there are subjects.

5This is the meaning of “Then God will be King over the entire earth”—His Kingship will be revealed. {It is clear to anyone who examines [the lesson] that the larger part of it is missing. The essential points are absent from the text, and I have not at all succeeded in comprehending these words.}
