I am currently going through Norman Doidge's book The Brain That Changes Itself.

It is a very inspiring scientific account on the ability of the brain to rewire itself to overcome disabilities (like the inability to astral project at will) and learn new skills. It is full of awe-inspiring real life examples of people who taught themselves to accomplish feats they couldn't achieve before.

I think the book is very much on topic for this web site which is dedicated to helping individuals learn Astral Projection. It is indeed a skill we could all learn.

I started this related wiki article
