In the 6th century BC, about the same time as Mahavira, Prince Siddhartha, who later came to be known as the Buddha, revolted against the religion as practiced in his day. Like Mahavira, he renounced the world and discovered that "kama" (desire) lay at the root of all evil. The cessation of desire he found possible only through knowledge. In the ideal state of existence, there is a release from the cycle of births and rebirths and this is called "nirvana". In this state, the ego of man is completely annihilated and he is free from joys and sorrows alike.
From India, the country of its origin, Buddhism spread to other parts of the world. It found a large following in the countries of eastern and south-eastern Asia.
