Salmi 39:7 Cabala: Zohar

And teshuvah is called life: "because from it there are results of life" (Prov. 4:23) - those [results] are Israel's souls.

And so the spirit rests, and an image with it, (104a) the same likeness that it had above, in that same image the spirit was created, in that same image it goes around in this world. For instance, it is written "but in the image a person walks" (Psalms 39:7). While the image is still found with the human, the human is still alive in this world, since they are joined as one. [Another version: and the two are joined as one). And King Solomon warned the human and said "until the day blows gently and the images/shadows fly" (Songs, 2:17) - two [tzelem outside and inside].

When [the soul] comes out to the world, that image/tzelem prepares itself for her and joins with her, and grows with her. As it is written: 'even in the image a person walks' (Ps. 39:7). And in the image the days of a human join, and are dependent on it - since it is written: 'for we are of yesterday, know nothing, since our days on the land are but a shadow/tzel' (Job 8:9). It is obvious that our days are a shadow. And from the moment that a woman conceives, to the moment she gives birth, humans have no idea of the deeds of the Holy One of Blessing, how great they are, and how awe-some. And this is why it is written 'how great are Your works, Ad-nai, etc' (Ps. 104:24).
