“In one way, having an enemy is very bad. It disturbs our mental peace and destroys some of our good things. But if we look at it from another angle, only an enemy give us the opportunity to practice patience. No one else provides us with the opportunity for tolerance. Since we do not know the majority of five billion human beings on this earth, therefore the majority of people do not give us an opportunity to show tolerance or patience either. Only those people whom we know and who create problems for us really provide us with a good opportunity to practice tolerance and patience.”
