If you actually wish others to follow what you say, it is necessary that you yourself follow what you want others to follow. Mere words of advice, rules of action, and the like are of no use. People do not believe in the preaching, or if some do, the strength is very meager. Living examples, which the person for whom they are meant can see before his eyes, can make a better impression and have the desired end, being something concrete, but precepts, which are things only in abstract, do not make good impressions upon the mind, or even if they do, it lasts only for a short time.

Mahatma Gandhi always believed in the saying that example is better than precept, and so he had thousands of followers. He never did what he asked others not to do. He was an apostle of creating examples in real terms.
