A Pratyekabuddha (Sanskrit) or Paccekabuddha (Pāli), literally "a lone buddha" , "a buddha on their own" or "a private buddha", is one of three types of enlightened beings according to some schools of Buddhism. The other two types are the Śrāvakabuddhas and Samyaksambuddhas. They are said to achieve enlightenment on their own, without the use of teachers or guides, according to some traditions by contemplating the principle of dependent arising. They are said to arise only in ages where there is no Buddha and the Buddhist teachings (Sanskrit: dharma; Pāli: dhamma) are lost. Many may arise at a single time. Unlike Supreme Buddhas (see bodhi), their enlightenment is not foretold.
