The Place of the Four Worlds ABYA and the Parsa between Atzilut and BYA
65) Thus it turns out that the essence of the TB was revealed exclusively in the Partzuf Nekiudot de SAG from the Tabur down to the Sium Reglav above the point of this world (HaOlam Hazeh). Know that all changes called forth by TB happened only in the Partzuf Nekudot de SAG and not above it.
As was already said above, because of the ascent of Malchut to mid-Tifferet of the Sefirot de Sof of the world AK, which cut off its vessels of reception at this point, the lower part of Tifferet and the NHYM de Sof de AK turned into an empty space. It happened not in AK, but in the Partzuf Nekudot de SAG de AK. The changes that took place in AK are considered the raising of MAN, which means that AK only performs these changes for creating the ten Sefirot of the world of the Nikudim. There were no changes in AK itself.
66) The division of the Partzuf Nekudot de SAG happened already during the TB (ascent of Malchut to Bina), i.e., before the raising of MAN and the Zivug made in the Nikvey Eynaim of the Rosh de SAG. This division occurred in the following way: Keter, Hochma, Bina, Hesed, Gvurah, and the upper third of Tifferet, down to its Chazeh, is the place of Atzilut; two thirds of Tifferet, from the Chazeh to the end of Tifferet, is the place of Beria; Netzah, Hod and Yesod is the place of Yetzira; and Malchut is the place of Assiya.
67) The place of the world of Atzilut is assigned to the spreading of the Upper Light down to Tifferet, where the Partzuf ends, i.e., the place of the ascent of Malchut Mesayemet to Bina, below which the light cannot enter. Thus, the place of the world of Atzilut ends in the Chazeh, i.e., at the boundary between the upper third of Tifferet and the lower two thirds of it. The new frontier, called the Parsa, is below the world of Atzilut.
Below the Parsa, the place was divided into three parts, although it was to be divided only into two: the ZON de Guf (ZA and Nukva) of NHY. Nevertheless, after a new Sium emerged in Bina de Guf (or Tifferet), only the ZON is below it. However, two thirds of Tifferet also descended under the Parsa. The fact is that Bina de Guf (Tifferet) in turn consists of its ten Sefirot KaHaB and ZON; and since ZON de Bina is the root of the ZON de Guf, ZON de Bina already possesses properties similar to those of ZON.
Hence, together with the ZON de Guf, the ZON de Bina is also under the Parsa. For this reason, Sefira Tifferet split in all its width in Chazeh de Partzuf, since Malchut, which rose to Bina, stands there, leaving the ZON de Bina (two thirds of Sefira Tifferet below the Chazeh) outside (under the Parsa).
That explains the distinction between the upper part of Tifferet above the Parsa, which refers exclusively to Bina, and the lower part of Tifferet (ZON), which is under the Parsa against its will. It is the root of the real ZON and in the future will have to provide them with the light. There is not much evil in it, since it emerged not by its free choice. It separated from the NHYM (actual ZON), positioned below it, and formed the world of Beria.
68) The ZON de Guf also split into two parts: ZA (NHY – Netzah, Hod and Yesod) became the world of Yetzira, while Malchut (or Nukva) formed the world of Assiya under Yetzira.
Here we have learned how, because of TB, the Partzuf Nekudot de SAG was divided and the place for the four worlds, Atzilut, Beria, Yetzira and Assiya, was formed. Keter, Hochma, Bina, Hesed, Gvurah and Tifferet down to the Chazeh formed the place for the world of Atzilut. The lower two thirds of Tifferet, from the Chazeh down to the end of Tifferet, formed the place for the world of Beria. Netzah, Hod and Yesod prepared the place for the world of Yetzira and Malchut created the place for the world of Assiya.
The common place for all the worlds begins at the point of the Tabur of the world AK and ends above our world, i.e., reaches a Sium Reglav de AK where the dressing of the Nekudot de SAG on the Partzuf Galgalta comes to an end.
