A "Buddha" is a title given to someone who has attained enlightenment, a state of profound understanding and liberation from suffering. The term is most commonly associated with Siddhartha Gautama, who became known as the Buddha after achieving enlightenment around the 5th century BCE in India. Buddhism, the religion founded on his teachings, emphasizes the Four Noble Truths and the Eightfold Path as a guide to overcoming suffering. Buddhas are revered figures in this tradition, and their teachings encourage followers to seek their own path to enlightenment, often through meditation and ethical living.
