Question: The weekly Torah reading Shemini (eight), speaks about this, that after seven years of dedication, on the day of the start of the service in the Tabernacle, Moses calls to Aaron and his sons to make special sacrifices. Moses and Aaron go out to bless the people, and the greatness of the Creator appears before all of the people of Israel. What is the meaning of the “eighth day?”
Answer: The first seven days correspond to the Sefirot: Hesed, Gevura, Tifferet, Netzah, Hod, Yesod and Malchut, whereas the eighth day is attainment, the elevation of Malchut to Bina. Bina is the discovery of the beginning of divinity among us.
In the Pirush HaGadol, it is said that the people were concerned about whether the Creator would be revealed. It depended on how they would go through the first seven days, in other words, the absorption of the lower characteristics that are found in a person (Hesed, Gevura, Tifferet, Netzah, Hod, Yesod), which enter into Malchut, and how Malchut reacts and absorbs these characteristics, as a result of which Bina will be revealed in it. This is called the revelation of the Creator because the Creator doesn’t exist on His own; He doesn’t exist.
We must understand the relativity of our discernments, our perception of reality. When we say that the Creator doesn’t exist, we mean that we cannot perceive Him, that we cannot define Him. From our point of view, He doesn’t exist as long as we haven’t become equivalent to Him with the characteristics of bestowal and love through the connection between us.
