This principle of opposites is at the very root of Creation, which is divided between the rule of the King and the Queen; Night and Day; the One and the Varied; the Eternal and the Evolving.
Rabindranath TagoreGreat suffering brings with it the power of great endurance. When sorrow is deepest all the forces of patience and courage are banded together to do their duty. So while we are cowards before petty troubles, great sorrows make us brave by rousing our truer manhood.
Rabindranath Tagore
