The six realms are different forms of existence in which we can take rebirth. They can also be thought of as psychological states we experience in our current life in the human realm.
A blissful, ethereal state in which one is supremely contented but oblivious to the suffering of others.
Jealous God Realm:
Fueled by ego and aggression, jealous or warring gods (asuras) are always striving to rise in power and position.
Passionate and perceptive, human beings experience many states of mind and have the most opportunity to free themselves from the cycle of death and rebirth (samsara).
A life of ignorant complacency and dullness, in which one doesn’t look beyond avoiding pain and seeking comfort.
Hungry Ghost Realm:
Incalculably frustrated by desires they cannot fulfill, hungry ghosts (pretas) are depicted with big bellies and tiny mouths.
A claustrophobic place of extreme hot or cold in which you can’t escape the torment of your own intense anger and hate.
