Tashlich, meaning "cast away," is a ritual performed on Rosh Hashanah (or during the 10 days between Rosh Hashanah and Yom Kippur) as a physical reminder of the human effort to cast away one's failures, sins, and regrets. By casting stones into the water and recalling the verse from Micah, "cast all our sins into the ocean's depths", we state our intention to return to our true selves.
