The Torah, “Leviticus” (Shemini), 10:16-10:17: And he was angry with Elazar and Ithamar, Aaron’s surviving sons, saying, “Why did you not eat the sin-offering in the holy place? For it is holy of holies, and He has given it to you to gain forgiveness for the sin of the community, to effect their atonement before the Lord!”
Eating meat is a very high level, which isn’t even allowed for all the priests.
We discern five levels in the spiritual Partzuf: the mind, the bones, the tendons, the flesh, and the skin. Attaining a state in which I begin to clarify the fourth level of the egoistic desire on the level of a priest is called eating the meat of the offerings that were burnt in the Tabernacle. It is a correction on a very high level, working with the attributes of in order to receive for the sake of the Creator.
Aaron’s sons Elazar and Ithamar were allowed to do so, meaning to ascend to a higher level thanks to the fall of their brothers Nadav and Avihu, who despite their fall discovered the desires by which such actions can be performed.
It is important to say that the Torah was written so that we can gradually follow it, and here we read about such high levels of the human spirit that we have no idea of because we cannot exit our ego. There the pure attribute of bestowal is in effect.
