The Torah, “Leviticus” (Shemini), 10:8-10:11: And the Lord spoke to Aaron, saying, “Do not drink wine that will lead to intoxication, neither you nor your sons with you, when you go into the Tent of Meeting, so that you shall not die. [This is] an external statute for your generations, to distinguish between holy and profane and between unclean and clean, and to instruct the children of Israel regarding all the statutes which the Lord has spoken to them through Moses.”
Wine symbolizes the Light of Hochma.
Everything depends on how we receive and perceive it. If I receive it in a vessel that is ready for bestowal, the Light of Hochma becomes the Light of life for me. But if I receive it in a vessel that isn’t ready, which means for myself, I get drunk and descend to the level of an animal, until the actual burning of the robes of priesthood, until the state of death.
We can understand this principle on the corporeal level when a person who loves to drink loses his human quality and lies about totally drunk.
