It therefore said (Bamidbar 11:9): “When the dew would descend onto the camp at night, the Munn would descend on top of it.” Meaning that it came down through the level of “His ‘locks of hair’ are wet from raindrops in the night”, that it came down through the level of ‘hairs’. This is because it comes from a very high spiritual level which is beyond the “Seder Histaleshelus-Orderly Progression of Spiritual Worlds” which descend in a way of “cause and effect”, which is why they can only be drawn down through the level of ‘hairs.’ In the case of the revelation of Hashem that is limited to the Hishtalshelus of specific spiritual levels there is no need to come through “hairs.”
For example, when a teacher has an idea that he wants to explain to a student, all he needs to do is take the idea and bring it down a couple levels to the student’s level of understanding, but the knowledge itself is basically the same. However, when a person fathers a child, the deepest spiritual aspect of the father becomes invested in the creative process, even though that process itself is completely physical. Because it is such a deep aspect of the person, it cannot be expressed through intellect (contemplation) or emotions (song or poetry), only through a physical act that is totally removed from bearing any resemblance to the spiritual essence that it carries.
Similarly, Hashem’s revelation from beyond Hishtalshelus cannot come down as it is directly; it can only be expressed in a “hairsbreadth revelation” that does not bear direct resemblance to the Infinite Source that it is expressing. This is the idea of the Munn and the Torah that both come from beyond Hishtalshelus and both come about through intense limitations until it’s not easily recognizable that the physical Munn and the Torah that discusses physical matters are expressing Hashem how He is beyond the limitations of time and space and spiritual levels.
