Torah, Deuteronomy 14:3 – 14:6: You shall not eat any abomination. These are the animals that you may eat: ox, lamb, and kid, gazelle, deer, and antelope, ibex, chamois, bison, and giraffe. And every animal that has a split hoof and has a hoof cloven into two hoof sections, [and] chews the cud among the animals that you may eat.
Spiritual correction is based on the action that is called Tzimtzum Bet (Second Restriction). Its essence is that the division of our desires happened in us thanks to the connection of the Upper Light (the quality of bestowal and love) with the lowest quality of a person (to receive for his own pleasure).
They are divided into weak desires, called desires to bestow, although we are not going to bestow anything in them, and the rougher ones called desires to receive.
Tzimtzum Bet states that we can work with other people on the level of small desires because we can help them with these desires, influence them, and relate to them correctly, and big desires we cannot use so those are restricted.
This is represented by the division between Kosher and non-Kosher animals. Kosher, hence, usable, are the desires that have indications that they are fit for bestowal. On the animal level, bull, sheep, goat, deer, etc. symbolize these desires in us.
All of them differ from the other animals on the basis of having cloven hooves, which indicates a clear division between qualities of bestowal and reception. Even if the quality of reception is manifested in them, it is so small that it works for bestowal. Furthermore, these animals constantly regurgitate their cud, which means that they have a closed cycle of food consumption. In our world, this is an external consequence of the Second Restriction.
Torah, Deuteronomy 14:6 – 14:7: And every animal that has a split hoof and has a hoof cloven into two hoof sections, [and] chews the cud among the animals that you may eat. But you shall not eat of those that chew the cud, or of those that have the split hooves: the cloven one, the camel, the hyrax, and the hare, for they chew the cud, but do not have split hooves; they are unclean for you.
If the animal is missing even one of the Kosher components that represents signs of Tzimtzum Bet, it cannot be used for food.
Thus, the Torah speaks about the correction of our egoistic desires and their use with the right intention. A person makes a restriction on his desires and seeks an opportunity to work with them further. Those of them that he can use “in order to bestow” are called Kosher, in other words, suitable for bestowal to others.
In our world, these qualities are represented in a certain way by some animals, fish, birds, and even plants. From everything that surrounds a person, he must select only what he can use with the intention to bestow.
