In plain words
Purity, they say, comes in two kinds: outer and inner. The purity you accomplish with clay and water is the outer one — it is called the purity of the body.
Close to the Sanskrit
"External and internal" — thus purity is said to be twofold. The purity performed by means of clay and water is remembered as the external, bodily purity.
