Lessons from the Commands after the Deaths of Aharon's Sons

QUESTION: Two commands were given after the deaths of Aharon’s two sons: do not drink intoxicating liquids; and do not enter the Holy of Holies at any time but the prescribed ones. What is the message of these commands to us?

ANSWER: Speaking to two types of Jews: יושבי אהל– connecting mainly to esoteric levels of learning (wine), tend to be disconnected from the earth; and בעלי עסק– worries of the world tend to disconnect one from the purpose of life, and needs set times to connect.
