Part 10 · Chapter 91

Keep this rule: wherever it is said and written that Aba and Yashsut, or Bina and Tvuna, are included together in one Partzuf in order to couple, as is known, it is always in the manner mentioned — that the Yesod of Atik, which is within Arich, splits open, and through this the whole becomes one single Partzuf. And as will be written, God willing, regarding the matter of the coupling of Aba and Ima for the purpose of the second Ibur [impregnation] of the Mochin of ZA, when they are included together in one Partzuf — it is likewise so. Remember this introduction.
