In Buddhism, Buddha (; Sanskrit: बुद्ध), "awakened one," is a title for someone who is awake, and has attained nirvana and Buddhahood. The title is most commonly used for Gautama Buddha, the founder of Buddhism, who is often simply known as "the Buddha". However, the title can also be used for others who have achieved enlightenment, such as the other human Buddhas who achieved enlightenment before Gautama, the five celestial Buddhas worshipped primarily by Vajrayana followers, and the bodhisattva named Maitreya, who will achieve enlightenment in the future and succeed Gautama Buddha as the supreme Buddha of the world.
The word Buddha means "the awakened one" or "the enlightened one". According to the Chinese Buddhist tradition, the title is literally translated as "the knowing one". "Buddha" is also used as a title for the first awakened being in a Yuga era. In most Buddhist traditions, Siddhartha Gautama is regarded as the supreme Buddha (Pali sammāsambuddha, Sanskrit samyaksaṃbuddha) of the present age.
