Condition of being fully spiritually awakened in Buddhism
In Buddhism, Buddha (, 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 nirvana ("blowing out"), bodhi (awakening, enlightenment), and liberation (vimutti, vimoksa). A Buddha is also someone who fully understands the Dharma, the true nature of all things or phenomena (dharmas), the ultimate truth. Buddhahood (Sanskrit: buddhatva; Pali: buddhatta or buddhabhāva; Chinese: 成佛) is the condition and state of a buddha.
