Tashlikh is the practice of standing before a body of water and tossing some fish food to represent the remaining sticky points within your persona that get in the way of your having/creating a good year. This is a gestalt type of experience, where you let go of clinging behaviors, memories and experiences. Good ritual facilitates desired change. The symbolism is like that of the scapegoat, you put into the crumbs what about yourself most needs to change, drop it into the water for the fish to transform. Water is the symbol for overflowing loving-kindness in Judaism, and is a powerful ritual tool for assisting in desired transformations.
