Reaction is the law of Nature, reaction is the result of every phase of action. When vice has its full run on the face of the globe, when it has reached its lowest depth and wildest reign, it spends its force, becomes weakened, allowing virtue to lift its head once more and build its palace of light upon its ruins. Vice is born of Tama, and virtue of Sattwa and the active force of both is Rāja. Time is the self-manifesting kaleidoscopic revolution of color-pictures on the transparent canvas of ether. After the deepest shades of dark colors are exhausted, there is a reaction of lighter colors. When Tama has exhausted its force, Sattwa asserts itself by natural law. This healthy reaction growing stronger will gradually evolve some order out of the chaos of the closing Kali. A portion of the people will get disgusted with the reign of utmost licence and inharmony, and, endowed with strong mental force to resist the influence of the age, will pierce the veil of darkness enveloping everything and see the light that dwells within. These will stimulate this reaction, and spread the discovered light among others groping in the darkness for that light. The four castes will be gradually established once more in some fashion. At this stage will be born in the village of Sambhalpur in India a Brāhman of great spiritual force, named Vishnujashā, and in time will become the father of the coming Incarnation of Vishnoo, one of the most powerful incarnations—Kalki. The Lord Kalki will rapidly grow into youth and spiritual power. At his mere mental call will come to him countless vehicles, armours, all kinds of weapons of war and soldiers. He will then lead them to battle against all the Mlechhas, robbers and tyrants, all over the world, who will fall shouting in agony before his mammoth sword. After extirpating them all, the hold will establish once again perfect order and harmony on the surface of the earth. After ruling the world as Emperor and infusing into humanity the spirit of highest spirituality, Kalki will make over the charge of the earth to the Brāhmans and disappear after entering a most beautiful forest.
