High Holidays in Brooklyn Taschlich: In the upcoming days Jews worldwide will be performing a ritual developed around the 13th century known as Tashlich “casting off”, a process of repenting and returning to G‑d.Jews traditionally proceed to a (any) body of running water, preferably one containing fish, and we symbolically throw (cast off) our sins into a source of water by reciting special verses.There are those who upon concluding the verses, throw small pieces of bread into the water, and shake the corners of their clothes out as a tangible act to achieve the spiritual goal of shaking sins from their soul.
