Buddha was the founder of the fourth largest world religion: at one time, one third of the human race were his followers.

He preached that if we freed ourselves from selfish desire we would become free from sorrow and not become the slave of material things.

But Buddha also realized that the extinction of personal ambition is difficult for most mankind.
In the meanwhile, Buddha urged to cultivate inner tranquility by pursuing the middle way between the extremes of self- indulgence and self- mortification, a doctrine which made him the earliest apostle of tolerance.
