It is said that if health is lost, something is lost. So to have a sound health, we must have the habit of cleanliness. We must clean our body, house and surroundings to have good health:- Washing makes us only externally clean. Cleanliness of mind is also essential to obtain godliness. God exists only in a pure mind. We can have a pure mind by speaking truth. To keep the mind pure we must be free from evil thoughts. Thus the mind will become the abode of God. Hence cleanliness is next to godliness. Cleanliness of mind will promote spiritual perfection and happiness.
