Significance for all of history of Eve being taken from Adam

Alshech (Bereishis 2:24): It would appear that the lesson we learn from the verse “ to this one is called woman – that it applies specifically to Adam and Eve who was actually taken from his body but not to future couples that would be born from them. That is why the Torah states next “Therefore a man should leave … and cleave to his wife”. In other words that this relationship applies all couples of men and women  that would ever exist that they should leave….That is because Adam  contained all the souls that would eventually come into the world in potential as is noted in Shemos Rabbah (40:3) and Avos deRabbi Nosson (31:3) regarding the verse Job (38:4) “Where were you when I laid the foundations of the earth? Similarly Eve Adam’s wife contained the souls of all women who would ever exist. In other words Adam and Eve included all the souls of Mankind and thus all the couples. As a result of this, the unity that existed between Adam and Eve exists in all future couples. Because they all had  their souls together from the very beginning and they are only lacking becoming one flesh  . this is the lesson to be learned. You should also note that the reason G-d created Eve from Adam and not from dirt was in order that the man should leave his parents and cleave to his wife which would not be true if she was made from dirt. That is because they would not have the natural attachment as we mentioned before. Alternatively we can say that Adam prior to having Eve taken from him had potentially all the souls of males that would ever exist and all the souls of women were contained in the rib. And according to the view that man was created with two faces, women’s souls were contained within the female face. Either way Adam and Eve were connected to all future couples by being one body Secondly the souls of the males were related to the yud. which is nature of man and that is why the word ish (man) is spelled with a letter “yud” . In contrast Women and the feminine nature is hey which is why the word women (isha) is spelled with a letter “hey”. To get to the point, it is possible to give her a name based on the body that she was taken from or based on the soul.  From the aspect of the body she could have been called adamah (dirt) because she was taken from Adam. But that is impossible because she was not from the dirt but rather she was derived from Adam’s bone and flesh, Therefore she was  given the name because of the soul. That is because the souls of the males and females were together in the first creation, and then the female aspect was made into a new entity. So it is better to call her isha (woman) to indicate she had been taken from the ish (man)  thus indicating both aspects. The predominance of the male souls and that they constitute a couple  that is why the verse contines with “therefore a man should leave” because the soul of all men is united with her soul in man. Regarding her he will desire her that is because desire comes from the soul and not from the body. Or Alternatively it can be said “This time … that is to say don’t be surprised  that a male can come from a female  because now there is unity in that she is bone of my bone … However from the aspect of the female and not from the male  she is not from the male essence  because it doesn’t say that she was made from the man but that she was taken from the man. That is he had certain potentials relevant to her in him from which she was taken. Consequently  she was not made from his male essence but rather from the feminine essence that he contained. Thus she was not from the male but only from his  bone and flesh. But the meaning of that she was taken from the male means from the properties of the rib.  Or we can say “This time “ alone is needed to indicate that bone of my bone and flesh from my flesh makes a relationship  with Adam and she was not made from dirt but from him. All this relationship requires is the reality that she is bone of his bone. Otherwise why state “And to this one he called woman because she was taken from the man” It was because all future couples were present in me and in all couples the souls of the man and woman are bound together. It is because of that fact that with all couples the man should leave his parents.  But  if someone says he doesn’t want to leave his parents. He only needs to be told what it says in Nida (31a) that the father and the mother make the body of their child while G-d makes the soul.  So if he is claiming that only in the case of Adam and Eve that the man should cleave to the woman but all future cases  why should they leave their parents and cleave to a stranger (an unrelated woman)?  To this the reply is that the facts are the opposite so that he should leave his parents because of what we have already explained. The proof is that cleaving to his wife is not in order that they  to produce a soul but rather to produce one flesh. In other words, a  man and his wife produce the body  while G-d makes the soul.  Thus the three are partners in producing children. Therefore how is it conceivable that their son should  cleave to them  the parents and not with his true mate who is related by her soul, that was united in Adam before Eve was taken  from him as we explained. This relationship is alluded by the fact that men search for a wife while women don’t search for a husband. Because woman was taken from Adam  and thus she is something he lost.and he needs to search for her and then cleave to her. Thus she was always his wife but he temporarily lost her, Alternatively from the aspect she constitutes his lost property, that from the first couple and for ever after, we have the concept of bashert (the daughter of ploni is destined to him) and she was lost to him sometime after he was born and therefore he needs to search and find her
