High-quality books on psychosis?

[Tristan12]

I remember hearing Leo talk about there being more effective spiritual-based solutions to things like psychosis and schizophrenia than what is offered from modern therapy, since the roots of those issues can only be explained from a more spiritual perspective, and they need to be resolved in that way.

Does anyone know of any books or resources talking about psychosis and other similar issues in this way? Its not something I deal with, I’m just interested in learning the psychology behind these issues explained from a spiritual perspective and not a western therapy one.

thanks
