The Flight of the Eagle - Jiddu Krishnamurti
It took me nearly five years to begin to understand Jiddu Krishnamurti. I ended up putting down his books in frustration several times because I didn’t understand what he was talking about. The Flight of the Eagle was the first book I was able to understand.
I think he speaks from a level of evolved consciousness that is a little difficult to understand at first. All I can say is return to him again and again until he makes sense to you, He is very helpful for one stage of awakening, once you have navigated your internal consciousness a bit.
