Cleanliness is to Godliness:Cleanliness is very important to keep your self very well organized, methodical and energetic. If the place you live is cleaned and organized you feel a kind of peace in your mind! The place you pray has to be clean or your mind will not concentrate. It is important to concentrate in ones life because then you can develop discipline. For eg: Yoga! you meditate... you need to have clear mind to meditate. And the environment you practice cleanliness will help you pray, meditate, live peacefully. 

Need/importance of cleanliness
: You need to practice cleanliness which is inter related to your health. You keep your self clean then you invite less problems. Every bit of effort you put helps the world keep clean. It is important to make sure in our minds cleaniness is needed in our everyday routine to grow our self in a better place. We are humans. We need to emphasis on the cleaniless and the importance of it. 

Effects of unhygienic conditions-diseases, Pollution: It can cause many problems by being unhygienic... simple cold to high risk in getting cancer. The germs are all around us. which is not seen by common eyes. With lenses it shows how many unhealthy germs are there and how fast they can spread if a person is unhygienic! Diseases start from cancer to asthama.... the pollution is one of the main cause for asthama....... chest conjetion.... lung cancer...... 

Suggestions: I would suggest every person to practice cleanliness.... If a person can relate it to peace of your mind every person will tend to keep himself/herself clean. Practice cleanliness if not like a obessessed individual in a moderate manner. 

Conclusion: I do not suggest anyone to be obessesed with cleaniless and make their life miserable in not touching anything or not breathing the air :) But whenever or wherever we keep ourselves clean and keep our environment clean and contribute ourselves even if it is in a small amount which will make the world a better place to live.
