The most important thing in Tibet is religion. Their religion, which is called Lamaism, is a sort of Buddhism peculiar to Tibet. Tibet might be called a theocracy, or a land where a god rules. For the ruler of Tibet, called the Dalai-lama, is considered no common man, but a real god on earth. Many centuries ago, in India, there lived a man named Gautama or Sakyi-muni. He was wise and good, and the new religion which he taught was a great improvement upon the Brahmanism of India. On account of his wisdom and goodness, he was called Buddha, but he never claimed to be himself a god. Since his death, however, many millions of people in many lands have worshipped him as a god.
