The three Machzorim described in the previous post relate to three Sephirot: Chesed, Gevura, Yesod. Machzor HaGadol relates to the seven remaining Sephirot - Malchut at ה, Hod at מ, Netzach at צ, Tiferet at ת, Bina at ם, Chochma at ץ, Keter at א Sofit (אות אלף סופית היא כתר).
Machzor HaGadol relates to the Parzufim of Olam HaAtzilut as follows. At regular א is Zeir Anpin. At ה is Malchut. Imma and Abba are at ם and ץ. Arich Anpin is at א Sofit.
Tikkunim occur in all Sephirot. Regarding Machzor HaGadol, the most notable Tikkunim are in the Sephirot of Zeir Anpin: Hod, Netzach and Tiferet. The driving Tikkunim are at Tzaddik (צמח), both צ and ץ (with ט of Chesed/Yesod: ט"צץ) for Netzach and Abba.
From Zeir Anpin to Malchut is ט, namely 2+3+4. This refers to טצ"ץ, which occurred at the Yom Kippur war, in year ת of the Machzor. At the first instance of Malchut after טצ"ץ a defining Tikkun of Malchut occurred.
From Malchut to Hod is צ, namely 6+7+8+9+10+20+30. The defining Tikkun in Hod is dependent on Malchut and on one Tikkun of צ after טצ"ץ. The Tikkun of Hod relates to Moshiach ben Yosef. The Tikkun of Hod in 5753 could not occur and Moshiach ben Yosef was killed.
From Malchut to Tiferet is צצ"ץ, namely צ plus 40+50+60+70+80+90+100+200+300. The defining Tikkun in Tiferet builds on Malchut and two Tikkunim in צ and one in ץ after טצ"ץ. Abba will strengthen Zeir Anpin.
From Malchut to Imma is צצץ"ץ, namely צצ"ץ plus 400+500. Imma will strengthen Malchut, and bring hatred to an end, in the wake of two Tikkunim in צ and two Tikkunim in ץ after טצ"ץ.
We will reach טצ"ץ צצץ"ץ in 5786.
Finally, Tikkun HaOlam, the Tikkun for Keter, is destined to occur at טצ"ץ אאאצצץ"ץ, where Aleph is Sofit (טצ"ץ צצץ"ץ plus 600+700+800+900). This is a special case, as this Tikkun is conditioned on itself. Therefore, it must "grow" and occur twice in a covert fashion before it occurs overtly. After that, at Aleph Sofit, one more than 999, is the final unison of left and right.
The Halacha is according to Abaye. We say Baruch Oseh Bereshit in the year of Zeir Anpin, having in mind the harmony of all cycles. This has absolutely nothing to do with the Sun at a physical level, or with the Moon, the planets, or the Mazalot. The Halacha is a compromise, though not because of the scientific inaccuracy of the length of Shmuel's year. The Halacha is a compromise because a priori one should bless the Creator upon perceiving Hanhagat HaOlam.
Baruch Oseh Bereshit
