In the [ Profound Meaning of the Lotus Sutra ] Chih-i points out a further correspondence between this [24:18] verse in the Mūlamadhyamakakārika and the multifarious characteristics of beings in the various realms of existence. Chih-i divided the realms of existence into ten interpenetrating realms or destinies: hell, preta, beast, asura, man, gods, śrāvaka, pratyekabuddha, bodhisattva, and buddha. These are not ten separate distinct worlds, but rather experiences or states of existence in one reality.

It may be more accurate to refer to these ten “destinies” as ten states of experience: hellish, to be full of insatiable appetite, brutish, combative, human, divine, ‘śrāvaka-like, pratyekabuddha-like, bodhisattva-like, and buddha-like. When one suffers the inevitable results of his or her misdeeds, one experiences the realm of hell. When one blindly follows sensual desires in a futile attempt to satisfy fleshly appetites, one experiences the realm of the preta. When one blindly follows one’s passions, one experiences the realm of beasts. When one fights with one’s fellow human being, one experiences the combative realm of the asura. When one joyfully listens to the music of Bach, one can experience the delightful realm of the gods. When one hears the teaching of the Buddha, one experiences the realm of the śrāvaka. When one performs an altruistic deed, one experiences the realm of the bodhisattva. When one has an insight into the true nature of reality, one experiences the realm of the Buddha. Chih-i’s claim that these realms are “interpenetrating” or “mutually inclusive” means that each sentient being experiences them all in accordance with its actions.

Also, each being has ten “suchlike,” or “such-as-it-is”, characteristics: appearance, nature, essence, power, activity, causes, conditions, results, retribution, and “ultimate identity of beginning and end.”
