Theravada Eschatology (Metteyya)

The Theravada lands of Burma, Thailand, Laos and Cambodia share with the rest of Buddhism a future Buddha, Metteyya (Pali for Maitreya), who will appear when the present teaching has been forgotten. The Cakkavatti-Sīhanāda Sutta lays out the mechanism: the dhamma declines age by age, the human lifespan shortens, the kings grow unjust, and at the bottom of the descent a single just ruler restores the law. Only then, long after, does Metteyya appear to preach what no one any longer remembers.

This is decline without catastrophe. The sāsana, the dispensation of the Buddha, is measured in thousands of years and is expected to fade not by destruction but by neglect. The architecture is close to the Japanese Mappō, but where Mappō sharpens into a dated deadline and a redirection of practice, the Theravada version stays a slow cosmological unwinding. The future Buddha is a consolation, not a schedule.

The material is thin on the ground as a constructed system. Burmese and Thai chronicles recount the decline and the coming of Metteyya in a national frame, tying the righteous king to the future Buddha, but there is no native terminal event and no world-ending fire. What the comparative survey would note is the same pattern found among the Jains and the Stoics: a tradition that makes time vast and downward, and so displaces the end beyond any political horizon. The world will not end. The teaching will simply be forgotten, and then a Buddha will return to remember it for us.

The Burmese case gives the motif a political form. The chronicles of the konbaung and earlier dynasties frame the righteous Buddhist king as the agent who holds the sāsana upright in his age, and the expectation of Metteyya underwrites the legitimacy of the ruler who protects the monkhood. In Thailand the same structure appears in the cult of the future Buddha and in the architecture of the great chedi, understood by devotees as a relic-site that will survive until Metteyya comes. The eschatology is thus present but soft: a consolation and a legitimation, not a date.

This is why the comparative survey files the Theravada lands beside the Jains and the Stoics rather than beside the Zoroastrians and the Jews. Where a tradition makes time vast and downward, it displaces the end beyond any political horizon, and the appetite for a terminal event drains away. The last Buddha has come; the next is named; the world between them is simply to be endured and maintained.
