Agnya-Setra is a class of worlds, according to the Buddhist system of religion. The Buddhists reckon that there are innumerable systems of worlds, each system having its own earth, sun, and moon. The space to which the light of one sun or moon extends is called a Sakwala, and includes an earth with its continents, islands, and oceans, as well as a series of hells and heavens. The Sakwala systems are divided into three classes, of which the Agnyn- setra denote those systems which receive the. ordinances of Buddha, or to which his authority extends. These systems are a hundred thousand kelas in number, each kela being ten millions.
