Three ages of the Dharma
three ages of the Dharma(正像末期). The Dharma of Śākyamuni Buddha will end after these three ages:
(1) The true Dharma age (正法) lasted 500 to 1,000 years after His passing. During this age, there were teachings, carrying out of the teachings, and attaining of fruits.
(2) TheDharma-likeness age (像法) lasted 500 to 1,000 years. During this age, there were teachings and carrying out of the teachings, but no attaining of fruits.
(3) The Dharma-ending age (末法) will last 10,000 years. During this age, the teachings will gradually vanish, and there will be neither carrying out of the teachings nor attaining of fruits.
Because people will no longer be receptive, the Dharma will be gone for a long time until the advent of the next Buddha. In the Bodhisattva in the Womb Sūtra (T12n384, 1025c15–19), fascicle 2, the Buddha prophesies that, after 56 koṭi and 70 million years, which means 630 million years (if a koṭi is 10 million), Maitreya Bodhisattva will descend from Tuṣita Heaven and become the next Buddha, bringing the Dharma to a renewed world.
