Kabbalah zu Ijow 3:31

Come and behold, how many afflictions befell Jacob to keep him from becoming infected by the Evil Inclination and to keep it distant from his lot. That is why he suffered punishments and afflictions, and had no quiet repose. He said, "I had no repose, nor had I rest, nor was I quiet; yet trouble came" (Iyov 3:26). Come and behold, how many afflictions do the righteous suffer in this world. Trouble after trouble, pain after pain, so that they can merit the World to Come.

Go and see: in the moment that a person comes to make oneself holy to pair oneself with one's female, with a holy friendship/connection, a holy spirit is stirred in that person, that includes male and female. And the Holy One of Blessing alludes to the appointed agent to the pregnancy of human beings, and gives into the agent's hand that spirit and informs the agent where the agent should place it. For instance, it is written: "the night said: 'a male has been conceived'" (Job 3:3). The night said, to that appointed agent, a male was conceived from so-and-so, and the Holy One of Blessing informed the agent about that specific spirit. Everything that was informed to the agent, the agent keeps.
