I have made a return to and delved deeper into eastern philosophy and literature that caught my interest back in the 90's when I was in my early 20's. I particularly am interested In Taoism and the poetry of Taoist monks and hermits of China.
There's something about both eastern philosophy and literature that goes well with sobriety- that requires sobriety almost. That crystal clear quality. Glass- like clarity.
I am interested in Buddhism as a philosophy, and there's a well known temple not far from where I live that I'd like to check out in more depth.
So, yes- I think studying that part of the world's religions and literature is a good sober pursuit.
