Only the very righteous go directly to Gan Eden. The average person descends to a place of punishment and/or purification, generally referred to as Gehinnom (guh-hee-NOHM) (in Yiddish, Gehenna), but sometimes as She'ol or by other names. According to one mystical view, every sin we commit creates an angel of destruction (a demon), and after we die we are punished by the very demons that we created. Some views see Gehinnom as one of severe punishment, a bit like the Christian Hell of fire and brimstone. Other sources merely see it as a time when we can see the actions of our lives objectively, see the harm that we have done and the opportunities we missed, and experience remorse for our actions. The period of time in Gehinnom does not exceed 12 months, and then ascends to take his place on Olam Ha-Ba.

Only the utterly wicked do not ascend at the end of this period; their souls are punished for the entire 12 months. Sources differ on what happens at the end of those 12 months: some say that the wicked soul is utterly destroyed and ceases to exist while others say that the soul continues to exist in a state of consciousness of remorse.

This 12-month limit is repeated in many places in the Talmud, and it is connected to the mourning cycles and the recitation of Kaddish. See Life, Death and Mourning.
