Yes this is the other complimentary truth that the greater the darkness, individually as well as collectively, the greater the possibility of Light. India is a classic example of a civilisation plunged into darkness for nearly 500 years hence it is destined to rise in an unprecedented way.
However it is the present arrangement of Nature. But if the souls of men could respond as the gopas and gopis of Vrindavan then the Mahabharata could be avoided and the darkness can be transformed into Light almost magically.
