Mental ilness, causes and apaya realms Mental illness is not uncommon in modern society, from mild to severe illness. Depression, (generalized) anxiety disorder, panic disorder and schizophrenia, to name a few. Do people with (long-term) mental illness are "destined" to be reborn in one of lower realms or they're seen just illnesses rather than unwholesome states of mind? What is the cause of mental illness from Dhamma point of view?
I think that unwholesome states of mind are conditioned and temporary.

It's difficult to generalise (i.e. I was told there are different results/experiences for different people) but if someone has a mental illness they may have seemingly unwholesome states of mind, and this condition might last for decades, for a lifetime -- but/or, a change in medication, a change in their social situation (friends), might condition a thorough "night and day" change in the states of mind even before the end of this life.

Sometimes it may seem that the range of (or the extremes of) experience is wider: i.e. a longer and more acute experience of a hell and/or a heaven (even in this life) than other more "normal" people will experience.

I'm not sure that Buddhism rightly talks about what's "destined" for people, i.e. perhaps it isn't correct to ask about it: because you can't predict the future and it may surprise you; because you should have some faith in the possibility of salvation, of becoming enlightened, of teachers, of refuge, of the three jewels; because there's some scope of agency and good (or bad) intentions, i.e. results are not predestined; and because the ability to see the effects of kamma on specific people is one of the Buddha's supernatural powers (and the fact that he did it sometimes doesn't mean that we should assume that we can).
