Third Gate. We named it "Is the Ein Sof [synonymous with] Keter", because it explains how the Ein Sof (G-d as the unknowable infinite and eternal) is thought to be Keter (Crown, the most supernal Sefira) according to many, and how Keter is excluded as a Sefira [by many], specifically R' Shem Tov ibn Shem Tov and his writings. Chapter 1 explains the notion of those who say the Ein Sof is Keter and the logical counter [to this notion].

Chapter 2 [continues to] counter this notion by means of many places in the Zohar.

Chapter 3 explains the thought of R' Shem Tov ibn Shem tov that Keter is not counted in the Sefirot, and the logical refutation supported by R' Shimon bar Yochai in the Zohar.

Chapter 4 explains and treats the Mishna in Sefer Yetzira that led to the [incorrect] conclusion of R' Shem Tov, and offer another interpretation.

Chapter 5 explains the aforementioned Mishna according to R' Shimon bar Yochai.

Chapter 6 treats the account of haIdra "The Other Forgotten Beam" to understand R' Shem Tov, and we provide an alternate reading.

Chapter 7 explains the above account in greater detail.

Chapter 8 explains the notion, secret, and explanation of the beautiful account of R' Shimon Bar Yochai, peace be upon him, from the Tikkunei Zohar: Genesis 2 "Two Chochma (Wisdom) and Binah (understanding); Three Awe of Hashem is the beginning of Da'at (knowledge)" .
