I’ve always struggled with the concept of Creator’s Throne and its reference in Zohar to Binah as I could find the right parallel for it. I therefore would like to share Rabbi’s Kaplan commentaries that clarify how Binah is connected to the Divine Trhone and how we, according to Baal HaSulam, coming closer to our Creator by resembling His actions.
The level of Throne is Binah – Understanding. It’s call a Throne because, in general, the concept of sitting is that of lowering. Therefore, when we say that G-d sits we actually mean that He is lowering His essence so as to be concerned with His universe and comprehended by it.
The Throne is the vehicle through which G-d seats and thus lowers Himself and this is the concept of Binah – Understanding, through which we comprehend G-d. This Throne is mentioned in Ezekiel 1:26, and Issaya 6:21.
Understanding is normally in the head. But it’s counterpart in the lower Sefirot is Gvura – Strength, which parallels the left arm. Thus this Throne is sometimes on the head and sometimes on the arm. This then parallels the Tefilin worn on both the head and the left arm.
Alluded to here are the Tefilin wore by G-d, mentioned in the Talmud. When we wear Tefilin, they parallel those of G-d, and they bring us near to G-d insofar as they help us to resemble Him. Of course, G-d’s Tefilin are not physical but refer to special concepts associated with appropriate Sefirot. In a essence us wearing Tefilin thus lowers G-d towards us and allow us to partake of His essence. This however is the concept of the Throne as mentioned above. This might seem to indicate that we should make a Tefilin in form of the chair and sit on them. But this would not be properly respectful.
The author [BAHIR] that G-d wears His Tefilin in open Mem. This is the concept of Bina – Understanding, the Supernal Mother (Yma Ilaa), when She descents to encompass and protect the lower Sefirot, which are her children. This descent is the mystery of Supernal Womb. The Tefilin worn on the head thus has straps which descent and encompass the body.
The numerical value of Mem is forty, alluding to the forty days in which the embryo is formed in the womb. This forty also parallels to the Ten Sefirot in each of the for boxes of the head Tefilin.
