Cleanliness is next to godlinessIt is very true that cleanliness is next to godliness. Here the question rises why is cleanliness is next to godliness and what is this cleanliness. Cleanliness  refers to remain clean both physically ( body ) and mentally( brain and heart). Cleanliness means removal of dirt from the body and heart and brain. When dirt is removed from the body it’s mean removal of disease from the body. 

Cleanliness also tells about our personality and our characters . If we wear clean cloths we get respect from the society. And if we don’t wear clean cloth we are not able to get respect from society. In every religions like Hinduism and Islam before worship cleaning is done . Also god loves those who keep themselves clean and  pure .
