I gave up! Mitra Ji, One more point I have forgotten to tell you. We always think our ancestors were great people. Those people who lived thousands of years ago were great people. This was not quite true. Most of the people in Vedic era were doing all shorts of nasty rituals like killing animals to praise god. The fossil of such rituals is our main and great festival Dashain. These people were considered Sudras as evil and principally there was nothing wrong to kill Sudras. Of course these people were Chariot dwellers and were comparatively advance at the time, however, those days were not certainly golden days of the race. By the time of Buddha, society was quite horrifying. So called upper caste people were so possessive to their caste and race. It was believed that if you see Sudra face to face that would bring misfortune. ... Buddha and his disciples tried their best to teach civilization.... His teaching produced the best civilized people of the world for some century......I can consider few centuries after Buddha were golden days for the Indian civilization. As I mentioned earlier Buddha said: दुस्सिलो हि बहुजनो ‍= अधिकांस मनिसहरु दुशिल (खराब) छन्। Not only today but all most of the time most of the people of the world were immoral. Perhaps this will be true for future as well. Discovery of Yoga itself was a great achievement in human civilization, however, it could never be for common people until westerners accepted it as a best exercise of the body in 20th century. Today, human civilization has jumped to a new chapter and this civilization can not be compared to our ancient civilization....If the world will not be destroyed by Global Worming or unseen comets....human civilization will jump to new chapter within a century.
