Musar su Levitico 11:2

Concerning the physical peculiarities which determine which living creatures we may eat: Rabbi Menachem HaBavli writes about the reasons for these various identifying marks of mammals, fish and fowl. It all has to do with the fact that, figuratively speaking, the souls are hewn from beneath the throne of G–d [the "throne" being perceived as sort of a Celestial quarry. Ed.]. Scales and fins on fish are perceived as a protective cover, shield. In a gloss the author makes the point that fish with scales and fins occupy the upper clear parts of the waters, whereas those which do not have fins and scales usually are found in lower, more murky parts of the water.

This is alluded to in 11,2: זאת החיה אשר תאכלו … אך זה לא תאכלו. Our sages say that Moses had difficulty understanding this paragraph and that G–d showed him what the various categories of animals looked like (Chulin 42). In Vayikra Rabbah 13,4 we are told that G–d showed Moses a head of fire, explaining that if the protective skin around the brain was pierced such an animal was unfit to eat regardless of the size of the hole. It is difficult to understand what Moses' problem was. We could have understood his problem if the chapter would have listed free-roaming animals which Moses had never seen. After all, Moses was not a hunter. However, the Talmud meant that Moses had difficulty understanding the reason for this legislation. He wanted to know why certain categories of animals were permitted, whereas others were prohibited. G–d showed Moses the positive spiritual impact which consuming certain animals would have on the people eating them, and the negative spiritual impact of certain other animals. He showed Moses the respective influence of those animals in the higher regions. Thereupon Moses understood why some categories of animals are termed "pure," whereas others are termed "impure." This is the mystical dimension of Deut. 14,23: ואכלת לפני ה' אלוקיך, "You shall eat in front of the Lord your G–d;" this is a reference to the "Table", i.e. a reference to the sacred element of the act of eating. Psalms 104,1: "Bless the Lord, O my soul," as well as Exodus 24,11: "They ate and drank and had a vision of G–d," are reminders of the impact consumption of food has on our spiritual faculties. This means that even when the Israelites consume food which has not first been specifically sanctified as a sacrifice, such meals are considered as if an act of spiritual significance had been performed. When Gentiles eat, on the other hand, this is a totally profane activity.
