Likutei Moharan 2:7/ליקוטי מוהר"ן ב׳:ז׳

17 . Now, all the Torah a person studies for the purpose of observing and fulfilling—all these letters are sparks of souls, and they are clothed within the prayer. There, they are renewed in an aspect of pregnancy. {As is brought in the Sefer HaGilgulim: All the souls enter Malkhut (Kingship) in the aspect of pregnancy and are renewed there.}

2This is the meaning of (Psalms 19:2), “The ShaMaYiM (heavens) declare the glory of the Almighty.” This refers to the Torah, which is aiSh (fire) and MaYiM (water)—the aspect of souls. These [souls] enter into the prayer, which is an aspect of “the glory of the Almighty,” as is written (Psalms 66:2), “Make glorious His praise”—corresponding to “For My praise, echtom from you.”

3Thus, these souls together with prayer <are termed> “glory” on account of [prayer’s] clothing <them>. Just as Rabbi Yochanan, who called his clothing “my glorifiers” (Shabbat 113a). As a result, it is called “the glory of the Almighty.” And they illuminate each other: the souls shine to prayer in an aspect of raising feminine waters, and prayer shines to the souls in the aspect of new insights. For she renews them in an aspect of pregnancy.

4And the souls, when clothed in prayer and brought to the tzaddik of the generation, are an aspect of “maidens, her companions who follow her, shall be brought to you” (Psalms 45:15).
