Kshatriya fought Kshatriya. If you were a Brahmin: which is to say, a theological student, or a man of letters, a teacher or what not of the kind--you were not even called up for physical examination. If you were a merchant, you went on quietly with your 'business as usual.' A mere patch of garden, or a peddler's tray, saved you from all the horrors of a questionnaire. Kshatriya fought Kshatriya, and no one else; and on the battlefield, and nowhere else. The victor became possessed of the territory of the vanquished; and there was no more fuss or botheration about it. And the vanquished king was not dispossessed, Saint Helenaed, or beheaded. Simply, he acknowledged his conqueror as his overlord, paid him tribute; perhaps put his own Kshatriya army at his disposal; and went on reigning as before. So Porus met Alexander without the least sense of fear, distrust, or humiliation at his defeat. "How shall I treat you?" said the Macedonian. Porus was surprised.--"I suppose," said he in effect, "as one king would treat another"; or, "like a gentleman." And Alexander rose to it; in the atmosphere of a civilization higher than anything he knew, he had the grace to conform to usage. Manu imposed his will on him. Porus acknowledged him for overlord, and received accretions of territory.--This explains why all the changes of dynasty, and the many conquests and invasions have made so little difference as hardly to be worth recording. They effected no change in the life of the people. Even the British Raj has been, to a great degree, molded to the will of Manu. Each strong native state is ruled by its own Maharaja, who acknowledges the Kaiser-i-Hind at London for his overlord, and lends him at need his Moslem or Kshatriya army.--All of which proves, I think, the extreme antiquity of the svstem: which is so firmly engraved in the prototypal world--the astral molds are so strong--that no outside force coming in has been able materially to change it. The Greek invasion goes wholy unnoticed in Indian literature.
