he holiest day of the year is approaching – Yom Kippur – the day when we fast, purify ourselves and pray. Let us examine the essence of this sacred day and its signiﬁ- cance in the Jewish yearly cycle. How is Yom Kippur supposed to inﬂuence a person’s life throughout the year? What can we take with us from Yom Kippur that can stay with us all year long and help us move forward in our personal journey? There is something we say repeatedly on Yom Kippur. Over and over again, we recite it together as a call to God and to ourselves – the 13 attributes of mercy.The story of the 13 attributes of mercy is told in the Book of Exodus. Several months after the Exodus from Egypt, the nation experienced an event that occurred only once in all of history: a public revelation of God before the entire nation. This event, Ma’amad Har Sinai, the Revelation at Mount Sinai, marked the beginning of the Torah being given to the Jewish nation.The Ten Commandments were given, and then Moses ascended Mount Sinai alone and stayed there for 40 days, during which he received the Torah in order to bequeath it to the nation waiting below.
