Rudra and Shiva reveal themselves as one. The Yogin sees God in all things, not only in all beings but in all events. He is the flood, He is the earthquake, He is Death that leads to a higher life, He is Pain that prepares us for a higher bliss. And sight is only possible to the calm heart and the unperturbed understanding. The materialist is not wrong when he holds good and evil to be merely operations of Nature which she uses impartially and without making a distinction, and that the distinction is an evolution in the human mind.
Evil is good disintegrating to prepare for a higher good.
That which is now tyranny, was once necessary to consolidate human society. What was once an ideal state of society, would now be barbarous and evil. Morality progresses, religion widens with the growing manifestation of that which is divine in the human race. As with the individual, so with the race and the world, evil tends to good, it comes into existence in order that men may reject the lesser good and rise to the higher. The problem of pain remains.
