Following previous post, I would like to clarify the story with “fallen angels”, i.e. the angels that took “daughters of earth” (women) and had relationships with them.
Obvious question arises – how could angles have any relationships with women if they don’t have means for such (if any) physical contact.
To understand this situation we have to look in the book of Zohar. The book of Zohar tells us that before Creator created Adam and Eve, two angels came to Him. The angles stated their case arguing that humans shouldn’t be created as they won’t be able to appreciate the enormous “shefa” (pleasure/love) that Creator is planning to give them. Yet, after listening to angles Creator did create human beings.
BTW this story is also aluded to in Torah when it talks about the creation of man, the exact phrase is “And WE shall make a man” – we in plural. Midrash tells us that when Moshe was writing Torah from HaShem, he begged not to use plural form arguing that people might twist the real meaning of it and thus sin by thinking that there is more than one force in the universe. To his statement HaShem replied – “those who want to sin, will find ways to sin”. Therefore the Torah was left with the “we” in plural to denote that HaShem consulted His angles before making the man.
Back to our fallen angels. After the man was created and humanity started to populate, people instead of worshipping HaShem started to worship idols and fell to one of the lowest spiritual levels (as the result of this state, flood took place leaving only Noach and his family). Zohar therefore tells us that when humanity fell to such low level the same angles appeared before HaShem pointing out that it was a mistake to make human beings and argued for full distraction of human life. To their argument HaShem replied: “If you think that it is so easy being human and to stay on the right path while not straying after temptations why don’t you try yourself”. As consequnce, these two angels where given human bodies and were sent down to earth. And as we can already guess, being in human body they couldn’t withstand human temptations and thus sinned with women of earth.
