30.52

Duration: twenty small kalpas (decreases and increases). In this kalpa, a thousand Buddhas appear in succession, beginning with Sūryaprabha Buddha and ending with Sumeru-lakṣaṇa Buddha (Bhaiṣajyarāja-sūtra). The Buddha said: 'After my parinirvāṇa, if there are those who diligently cultivate merit, practice the various samādhis, recite Maitreya's name, and practice the six dharmas (the practice of the six perfections), they will definitely be born in the Tuṣita Heaven. They will also follow Maitreya to descend and be born in Jambudvīpa to be the first to hear the Dharma; in future ages they will encounter all the Buddhas of the Fortunate Kalpa, and in the Constellation Kalpa they will also encounter the Buddhas and receive the prediction of bodhi' (Maitreya-upapatti-sūtra).
