A summary of the major activities of the Kohen Godol on Yom Kippur in chronological order, with reference sources. It includes a small diagram of the Temple, an explanation of the symbolisms of the Avoda and other elements and events related to the Temple and Temple service, an "Atonement" chart, and some brief information on the differences between the Amitz Coah and Atoh Conantoh versions of the Avoda as recited during the Yom Kippur Mussaf service.
Tzvee Zahavy adds, "Rav Soloveitchik said that the Avodah was one of his favorite tefillot. One of my favorites as well. It is a quintessential expression of priestly archetypal prayer within our synagogue devotion. By knowing how the ancient priests sought atonement we may find another path to our own repentance."
