But now we must go back three centuries in our story to tell of a great teacher who came near to revolutionizing the religious thought and feeling of all Asia. This was Gautama Buddha, who taught his disciples at Benares in India about the same time that Isaiah was prophesying among the Jews in Babylon and Heraclitus was carrying on his speculative enquiries into the nature of things at Ephesus. All these men were in the world at the same time, in the sixth century B.C.—unaware of one another. This sixth century B.C. was indeed one of the most remarkable in all history. Everywhere—for as we shall tell it was also the case in China—men’s minds were displaying a new boldness. Everywhere they were waking up out of the traditions of kingships and priests and blood sacrifices and asking the most penetrating questions. It is as if the race had reached a stage of adolescence—after a childhood of twenty thousand years. The early history of India is still very obscure. Somewhen perhaps about 2000 B.C., an Aryan- speaking people came down from the north-west into India either in one invasion or in a series of invasions; and was able to spread its language and traditions over most of north India. Its peculiar variety of Aryan speech was the Sanskrit. They found a brunette people with a more elaborate civilization and less vigour of will, in possession of the country of the Indus and Ganges. But they do not seem to have mingled with their predecessors as freely as did the Greeks and Persians. They remained aloof. When the past of India becomes dimly visible to the historian, Indian society is already stratified into several layers, with a variable number of sub-divisions, which do not eat together nor intermarry nor associate freely. And throughout history this stratification into castes continues. This makes the Indian population something different from the simple, freely inter-breeding European or Mongolian communities. It is really a community of communities. Siddhattha Gautama was the son of an aristocratic family which ruled a small district on the Himalayan slopes. He was married at nineteen to a beautiful cousin. He hunted and played and went about in his sunny world of gardens and groves and irrigated rice-fields. And it was amidst this life that a great discontent fell upon him. It was the unhappiness of a fine brain that seeks employment. He felt that the existence he was leading was not the reality of life, but a holiday—a holiday that had gone on too long. The sense of disease and mortality, the insecurity and the un-satisfactoriness of all happiness, descended upon the mind of Gautama. While he was in this mood he met one of those wandering ascetics who already existed in great numbers in India. These men lived under severe rules, spending much time in meditation and in religious discussion. They were supposed to be seeking some deeper reality in life, and a passionate desire to do likewise took possession of Gautama.
