Handbook to Higher Consciousness
I just wanted to recommend the Handbook to Higher Consciousness written by Ken Keys Jr. I believe it was written in the 70s so it's a little old. But it is interesting to see how even after several decades that the same ideals exist. It's not specific for SA but helps with positive thinking which is needed all around. My therapist gave it to me to try and it has pretty much become my bible for good living.
I think the point for SAs like us, is that we see other folks as threats. This book helps to understand the world is not about "Them vs Us" but that it is only about "Us". Of course, there's much more to it, but you'll have to dig into it yourselves. Give it a try.
