Praying Surface is a term used to describe a RUG or carpet that is used for prayer. It is usually made of a soft material such as wool, cotton, or silk and is often decorated with intricate designs. The RUG is placed on the floor in front of an altar or shrine and is used as a place to kneel and pray. The term 'RUG' is an acronym for the words 'RUG Under God, ' which is a reminder that prayer should be done with humility and reverence.
