The Lord is always true and pure. In order to be one with Him, it is necessary for us to be pure of heart and tongue. That is why almost al the religions emphasize on observing cleanliness and purity. Amongst the Muslims, wazoo (ablutions) are considered necessary before saying prayers (Namaz). With it, the outside of the body is cleansed. By keeping fasts, the inside of the body is cleansed. The Sikhs, the Nirmalas and the Namdharis also strongly emphasis on bathing by which the body, mind and intellect become active to some extent and one is inclined to worship.
