There is nothing more important than an example. It leads us to do good deeds which would be impossible without this example. Therefore, if we use dissipated or passionate or cruel people as examples, it destroys our soul. The contrary is also true.
Those who do not think independently are under the influence of somebody else who thinks for them. If you give your thoughts to somebody else, it is a more shameful slavery than if you give your body to someone to possess.
If you desire to follow someone as an example, as many other people do, first stop and think whether it is worthwhile to follow the path to destruction.
— Dhammapada, a book of Buddhist Wisdom
Evil influence can be destroyed only by good influence. And the way to receive a good influence is to have a good life.
