Tashlikh is a Hebrew word meaning "casting off" and is a Jewish tradition performed on the afternoon of Rosh Hashanah. The custom is to go to a large, natural flowing water (such as a river, lake or sea, etc), and 'throw' into it all previous year's sins. This is an interpretation of the bible ceremony: "You will cast all their sins into the depths of the sea." (Micah 7:18-20).
