Maitreya is the future buddha, the buddha who will follow our present Buddha Sakyamuni. For more than two thousand years Maitreya (Pali Metteyya) has been an inspiration for Buddhist devotees who look forward to his coming and aspire to meet him and receive his blessings and teachings. Their devotions have animated art, ritual, meditation practice and literature across Asia. The Theravamsa of Sri Lanka and South-East Asia transmits a Chronicle of the Future' (Anagatavamsa) in a bewildering number of recensions. Written in Pali, the Chronicle' is a paean of the golden future that Maitreya will inaugurate for those who practice sincerely. The present volume contains a study, a critical edition, and an annotated translation of a commentary on the Chronicle', the Amatarasadhara, or Stream of Deathless Nectar' composed in Pali by the Sri Lankan elder Upatissa.
