unsurpassed enlightenment ［無上菩提］ ( anuttara-sambodhi; mujō-bodai): Also, supreme enlightenment or supreme perfect enlightenment. The enlightenment of a Buddha. The Sanskrit anuttara means “unsurpassed.” A Buddha’s enlightenment is so called because it is the highest and supreme among all levels of awakening gained through Buddhist practice. Bodhisattvas make four vows when they first resolve to embark upon the Buddhist practice. These four vows are known as the four universal vows, one of which is to attain unsurpassed enlightenment.
