Zohar Pinchas, Vol. 20 (English)/Vol 15 (Hebrew)
The Zohar discusses four periods of salvation and connects them to the four cups of wine we drink on the night of the Seder that is the night of the full moon of the month of Nissan (Aries).
The codes for the years are 1256, 1260, 1266 and 1272.
Obviously these and other numbers in this commentary are not calendar dates but codes related to spiritual forces.
The Redemption will come through the four letters of the YHVH name. YHVH ‘rides’ on the four Holy Creatures of the Holy Throne, Lion, Ox, Eagle and Man.
“כִּי תִרְכַּב עַל-סוּסֶיךָ, מַרְכְּבֹתֶיךָ יְשׁוּעָה. ”
“You will ride on your horses, your chariots of salvation”
“יְהוָה מֶלֶךְ, יְהוָה מָלָךְ; יְהוָה יִמְלֹךְ, לְעֹלָם וָעֶד”
“YHVH King, YHVH was King, YHVH will be rein forever and ever.”
The three names with 12 letters represent the control over the three columns. The 12 is the aspect of the 12 tribes and the four flags that rose above the camps of the Israelites for their protection. 72 years after the 1200 will be the Redemption.
The 72 names receive their energy from the 12 letters of the three names. 72 divided by 12 gives us 6, that refers us to the six Sefirot of Zeir Anpin.
When the 72 goes to the three columns of Chessed, Gevurah and Tiferet we have 24 in each column. This flow of light connects 3 camps of angels that each have 24 forms and each say קדוש קדוש קדוש, Kadosh, Kadosh, Kadosh (Holy Holy Holy). When the light of the 72 shines on the 3 camps of angels the name of 42 (Ana B’Koach) awakens to remove Amalek, that is the aspect of all negativity in the world.
Rabbi Ashlag comments that all the numbers mentioned in this Zohar sections are openings for all of us to do repentance, Teshuvah, and merit the Final Redemption.
