Kidusha in Chazars Hashatz (part one). Kidusha (1). An introduction to Kidusha. The Zohar says that Kidusha is Biblical and is learned from the same Possuk from which we learn Mesiras Nefesh Al Kidush Hashem. Kidusha is about creating a Merkava (seat) for Hashem’s manifestation as the various levels of malachim do. The different Nuschaos, and the fact that in later times the Nusach was actually abridged (in the weekdays). The Nusach Ashkenaz, to say during the week “Nikadeish” (we will [on shabbos] sanctify,) indicates a Yeridas Hadoros, and a decreased ability to be Mekadesh Hashem in this way.
