An Indian religious teacher is often referred to as a BUDDHA. The term BUDDHA is derived from the Sanskrit word 'budhi', which means 'to awaken'. The BUDDHA was an Indian spiritual leader who lived in the 5th century BCE and founded Buddhism. He taught that suffering was caused by attachment to worldly desires, and that the path to enlightenment was through meditation and self-discipline. He also taught the Four Noble Truths and the Eightfold Path, which are the core teachings of Buddhism.
