Fair enough, I am kinda scared about everything these days.

Which one of his books should I read (first)?

Ya fear of the unknown is not even anything uncommon for sure.

Honestly ive only read "the power of now",

Which I later learned was very mainstream popular, so I probably would have prejudged it had I knew. While not really original ideas he packages the concepts into very good words, so it made something click, for me at least, where other books hadn't.
