בריאת העולם ותחית המתים - אדון עולם ואקדמות
The Piyut of “Adon Olom Asher Molach – Master of the universe, Who reigned” which we say every morning begins from “Before any form was created” the creation of the Malochim, of the world, which was created by Hashem Himself, until ”Vacharei Kichlos Hakol Livado Yimloch Noroh – He the Awesome One, will reign alone.” This is a proclamation that Hashem {G-D} is timeless, infinite, and omnipotent. Rav Pinchos of Koritz ZY”A says in Sefer Imrei Pinchos, that the Piyut of Adon Olom was authored by Rav Hai Goan, and it is a great praise which begins from before the creation of the world, and finishes after Techiyas Hameisim (Resurrection of the dead) – V’im Ruchi Giviyosi. And in between there are also great secrets. So too, He said in Akdomos which is recited on Shavuos, it starts from the Creation of the world, and ends after Techias Hameisim.
