1. Yom Kippur (the Day of Atonement) is a major Jewish holiday of individual self-enhancement spiritually and perpetually, transforming acrimony and vindictiveness into forgiveness, peace of mind and peaceful coexistence between God and human beings, but especially between fellow human beings. While Yom Kippur prayers request forgiveness for sins committed against God, it is customary to dedicate Yom Kippur's eve to repentance for sins committed against fellow human beings.
