Gandhi Philosophy

In his autobiography, Gandhi ji tells about a Gujarati stanza which was his guiding principle. Here is its translation: 

Return Good for Evil

For a bowl of water give a goodly meal;

For a kindly greeting bow thou down with zeal;

For a simple penny pay thou back with gold;

If thy life be rescued, life do not withhold;

Thus the words and actions of the wise regard;

Every little service tenfold they reward;

But the truly noble know all men as one,

And return with gladness good for evil done.

Is not it wonderful?
