History and Teachings of Nichiren Buddhism, p 108-109The truth of suffering states that all existence — the twenty-five states of existence, six paths, and the triple world — is bound by the suffering of repeated rebirth. Consequently, suffering is the objective circumstance of all existence.
The twenty-five states of existence classify the world into twenty-five parts, outlined as follows:
The Four Evil Destinies
1. Hell-dwellers
2. Hungry ghosts
3. Animals
4. Fighting demonsThe Four Continents

6. Jambudvīpa in the south
7. Aparagodānīya in the west
8. Uttarakuru in the northThe Six Heavens of the Desire Realm
9. Heaven of the Four Heavenly Kings
10. Heaven of the Thirty-three Gods
11. Heaven of Time
12. Heaven of Contentment
13. Heaven of Delight in Creation
14. Heaven of Controlling the Creations of OthersThe Seven Heavens of the Form Realm, including the Four Heavens of Meditative Absorption
15. Heavens of Great Brahma
