Six Realms of Existence
The six possible states of rebirth based on karma.
Beings cycle through six realms: gods, jealous gods, humans, animals, hungry ghosts, and hell beings. Each realm results from particular karmic patterns and mental states.
As long as one is in samsara, one circles through these realms.
Understanding the six realms motivates escape from samsara.

- What Tibetan Buddhism says about envy and comparison
One of the six realms of rebirth belongs to the asuras, the jealous gods, who have almost everything and fight endlessly over what the gods have instead. Envy is not classed as a passing mood here but as a world with its own karmic causes, which you can be born into and live in.
