Fourth, the establishment of lifespan is divided into three: first, distinct explanation of the lifespan in the three realms; second, explanation of premature death; third, explanation of the remnant body. The desire realm is divided into seven: 1. humans; 2. devas; 3. great narakas; 4. asuras; 5. animals and ghosts; 6. cold narakas; 7. peripheral and solitary [hells]. Due to differences in grades of good and evil karma, lifespans also differ; these should be examined in detail (these numbers are easy and thus not discussed).
