Kabbalah zu Bereschit 6:3

For the sake of the First Human, and his coupling, detrimental to the Holy Blessed One, and regarding this we explain, when they come from above, until the Will comes before the Holy Blessed One, if the human has merited, they bring his pair, and if not, they separate her from him, and bring her to another/behind, and they give birth to children that are not proper. And regarding this it is written "My spirit will not remain in the human forever" (Gen. 6:3). What is 'My spirit'? You would expect 'his spirit' to be written, there are two spirits, when the pairs go out, they do not remain as one, and regarding this it is written 'and she gives birth to a male' (Lev. 12:2), and this does not include both male and female, according to the ways of the world, as we brought this about.
