These old philosophies are preserved in the _Upanishads_, or Instructions. The main idea in these diverse systems--the _Sankhya_, the _Vedanta_, etc.--is, that the soul's notion of itself as separate from the supreme, impersonal being, is the fallen state. This duality must be overcome. Conscious of its identity with the Supreme, the soul enters into _yoga_, or the state of unison with the Infinite. He who is thus taken away from the illusions of sense, or the _yogin_, is free from the power of things perishable. Death brings a complete absorption into the source of all being. It is the bliss of personal extinction. This sort of philosophy attached great value to contemplation and self-renunciation. It led to a light esteem of ritual practices and ceremonies. BUDDHISM. The Brahminical system has not ceased to maintain its supremacy in India since the time when it was presented to view in the law-codes. But it has not escaped alteration and attack. New movements, religious and political, have appeared to modify its character. Of these, Buddhism is by far the most memorable. THE LIFE OF BUDDHA.--Of the life of Buddha we have only legendary information, where it is impossible to separate fact from romance. The date of his death was between 482 and 472 B.C. He was then old. He belonged to the family of Gautamas, who were said to be of the royal line of the Çâkyas, a clan having its seat about a hundred and thirty-seven miles north of Benares. The story is, that, brought up in luxury, and destined to reign, he was so struck with the miseries of mankind, that, at the age of twenty-nine, he left his parents, his young wife, and an only son, and retired to a solitary life to meditate upon the cause of human suffering. From Brahminical teachers he could obtain no solution of the problem. But after seven years of meditation and struggle, during which sore temptations to return to a life of sense and of ease were successfully resisted, he attained to truth and to peace. For forty-four years after this he is said to have promulgated his doctrine, gathering about him disciples, whom he charged with the duty of spreading it abroad. THE BUDDHISTIC DOCTRINE.--Buddhism was not a distinct revolt against the reigning system of religion. Buddha left theology to the Brahmans. Indra, Agni, and the other divinities, and the services rendered to them, he left untouched. Being an anchorite, he was not required to concern himself with the rites and observances in which others took part. His aim was practical. His doctrine, though resting on a theoretical basis, was propounded simply as a way of salvation from the burdens that oppressed the souls of men. Nor did he undertake a warfare against caste. The blessing of deliverance from the woes of life he opened to all without distinction. This was the limit of his opposition to caste.
