Bhadrakalpika Sūtra. A large Mahāyāna sūtra which lists the details of the thousand Buddhas of the Good Aeon (most not known outside of this text) giving their names, places of abode, entourage, and so forth. Due to its length, it is a rather tedious work to read and perhaps functioned more as a kind of devotion or litugical composition.
