Well I'm probably not an Arya, but I do have a mental illness,and I think a mental illness is just like any other disability, diabetes, being paralysed in a wheelchair, having heart disease etc etc, They are all something physically wrong with how the body works, I don't see how any of these situations should stop one from reaching or coming close to enlightenment. Of course mentally ill people might be more likely to be deluded into thinking they are enlightened when they are not. But if you read the history books,all kinds of religious saints were mistaken for crazy or had their crazy periods, Ramakrishnan is one I remember reading about. Lots of Tibetan saints did some crazy things. As a mentally Ill person, we have to struggle with people treating us differently; "less than normal" when in reality mentally people actually can and might have abilities normal people do not, especially in their spirituality. So put all your predjudices aside and treat people as equally able to grow, whether they actually do grow or not.
18 years ago I made one of the most important decisions of my life and entered a local Cambodian Buddhist Temple as a temple boy and, for only 3 weeks, an actual Therevada Buddhist monk. I am not a scholar, great meditator, or authority on Buddhism, but Buddhism is something I love from the Bottom of my heart. It has taught me sobriety, morality, peace, and very importantly that my suffering is optional, and doesn't have to run my life. I hope to give back what little I can to the Buddhist community, sincerely former monk Johnhttp://trickleupeconomictheory.blogspot.com/
