Definition: Tansu, also known as "Bread," is a word in ancient Greek language that refers to grains, including wheat, barley, and rye. It signifies a unit of measure for large amounts of food. In Jewish tradition, Tansu was traditionally associated with unleavened bread, which symbolizes the spiritual separation between light and darkness (Tannas, "darkness"), and it is also mentioned as one of the ingredients in the baking process.
