In Buddhism, Buddha (/ˈbuːdə, ˈbʊdə/, which in classic Indic languages means "awakened one") is a title for those who are spiritually awake or enlightened, and have thus attained the supreme goal of Buddhism, variously described as awakening or enlightenment (bodhi), Nirvāṇa ("blowing out"), and liberation (vimokṣa). A Buddha is also someone who fully understands the Dhārma, the true nature of all things or phenomena (dhārmata), the ultimate truth. Buddhahood (Sanskrit: buddhatva; Pali: buddhatta or buddhabhāva; Chinese: 成佛) is the condition and state of being a Buddha. This highest spiritual state of being is also termed sammā-sambodhi (Sanskrit: samyaksaṃbodhi; "full, complete awakening" or “complete, perfect enlightenment”) and is interpreted in many different ways across schools of Buddhism.
The title of "Buddha" is most commonly used for Gautama Buddha, the historical founder of Buddhism, who is often simply known as "the Buddha". The title is also used for other sentient beings who have achieved awakening or enlightenment (bodhi) and liberation (vimokṣa), such as the other human Buddhas who achieved enlightenment before Gautama; members of the Five Buddha Families such as Amitābha; and the bodhisattva Maitreya, known as the "Buddha of the future who will attain awakening at a future time."
