48. The establishment of Atika Kadisha is such that it was established as one structure that includes all structures. It is supernal, hidden Chochmah, NAMELY, THE THIRD HEAD OF ARICH ANPIN, which incorporates all the rest, and is called supernal, hidden Eden. It is the brain of Atika Kadisha. This brain expands in every direction and from it spreads another Eden, SUPERNAL ABA AND IMA THAT ARE LOWER EDEN. From that Eden CHOCHMAH is engraved AND STARTS TO REVEAL ITSELF IN YISRAEL- SABA AND TEVUNAH, ZEIR ANPIN AND MALCHUT, WHICH IS THE SECRET OF LOWER CHOCHMAH, WHERE CHOCHMAH IS REVEALED.
