If we want to improve our society, bring some good changes to it. We must first make such improvements and changes in our own homes. If you preach the value of cleanliness to your neighbors and keep your own home dirty, it will not make others follow you or accept your changes; it is always better to follow them first in your own life. Charity begins at home, which means that you start all the good things from your home so that others can follow you in letter and spirit.
