BUT...WHAT IS...

TEN WORLDS

Ten distinct realms or categories of beings referred to in Buddhist scriptures. 

From the lowest to the highest, the realms of (1) hell, (2) hungry spirits, (3) animals, (4) asuras, (5) human beings, (6) heavenly beings, (7) voice-hearers, (8) cause-awakened ones, (9) bodhisattvas, and (10) Buddhas. 

The Ten Worlds were viewed originally as distinct physical locations, each with its own particular inhabitants. The Lotus Sutra, however, teaches that each of the Ten Worlds contains all ten within it, making it possible to interpret them as potential states of life inherent in each individual being. In other words, from the standpoint of the Lotus Sutra, the Ten Worlds indicates ten potential states or conditions that a person can manifest or experience. The mutual possession of the Ten Worlds is a component principle of three thousand realms in a single moment of life, which T'ient'ai (538-597) set forth in Great Concentration and Insight.
