Buddhism originated from Siddhartha Gautama, a Hindu prince who saw suffering in the world and sought to end it. He achieved enlightenment and taught the four noble truths: that life involves suffering, suffering is caused by desire, desire can be overcome, and the eightfold path provides a way to overcome desire. The eightfold path involves right view, intent, speech, action, livelihood, effort, mindfulness, and concentration. Its goal is nirvana, the liberation from suffering and the cycle of rebirth through living morally and meditating to gain enlightenment. Today, Buddhism is practiced by many monks in Asia, with the Dalai Lama as its most famous modern teacher.
