In later texts the number of former buddhas becomes gradually multiplied: the Buddhavaṃsa lists twenty-four, the Lalitavistara Sūtra fifty-three, the Larger Sukhāvatīvyūha Sūtra eighty-one, and the Mahāvastu five hundred. Eventually, in accordance with the expansive cosmology and mythology of the Mahāyāna, their number becomes incalculable. See also DĪPAṂKARA; MAITREYA.
