Vidui is a Jewish practice of confession, traditionally recited during the Yom Kippur service. It involves acknowledging sins and seeking forgiveness from God, emphasizing personal accountability and spiritual cleansing. The ritual is often performed in a communal setting, allowing individuals to reflect on their actions over the past year. Vidui can also be recited during other occasions, such as before death, to help the individual attain a sense of peace and reconciliation.
