Additionally, on the topic of strengthening one’s hitbodedut practice and reciting supplications and entreaties Rebbe Nachman said:

The act of speaking is very effective for spiritually rousing a person. Even if it seems to him that he has no feelings, when he speaks many inspirational words, supplications, entreaties, and the like—the very act of speaking is the concept of revealing and rousing his heart and soul for God. This is as in (Song of Songs 5:6), “My soul came forth when he spoke”—the speaking is itself a revelation of the soul and the heart.

Thus, sometimes, as a result of a great deal of speaking, even when it is without any feeling, one’s heart and soul are afterwards greatly inspired. The principle is that the act of speaking in itself has great power.
