The joyous mood is infectious and therefore brings success. But joy must be based on steadfastness if it is not to degenerate into uncontrolled mirth. Truth and strength must dwell in the heart, while gentleness reveals itself in social intercourse. In this way one assumes the right attitude toward God and man and achieves something. Under certain conditions, intimidation without gentleness may achieve something momentarily, but not for all time. When, on the other hand, the hearts of men are won by friendliness, they are led to take all hardships upon themselves willingly, and if need be will not shun death itself, so great is the power of joy over men.
