The Torah, “Numbers” 5:14: But a spirit of jealousy had come upon him and he became jealous of his wife, and she be defiled, or, a spirit of jealousy had come upon him and he was jealous of his wife, and she be not defiled.
A person makes great efforts to be connected to the Creator by his desires that are aimed at the goal. When he enters the next level of Ibur (gestation) he thinks that he can hold on in this state, but suddenly something tragic happens and he falls. He already enters the next level, the upper Partzuf and suddenly he falls because some of his desires have become detached from the right intention. There is nothing you can do here but examine your desires.
Comment: It turns out that everything in this world stems from spiritual roots?
Answer: Nothing in this world can be any other way! What is more, our world is very flat.
There are different states in the spiritual world, including jealousy and embezzlement. A person uses anything he can for his spiritual ascent. Nothing happens in vain in this process, while in our world a man may kill himself and his woman because of his jealousy. If a couple are partners in a certain search and suddenly she is physically attracted to another man, she detaches herself from the general idea, from the mutual yearning to her man and he cannot attain the goal that they have set for themselves without her.
It turns out that she has betrayed their common motion and has totally killed his state, but without her it is impossible to fulfill the spiritual correction because she is half of the common Partzuf.
