Poor old man. You managed with your zimmer frame into here? It's not the Badlands. Too bad you lost your way.
Happiness and consciousness can be achieved without an NDE or OBE but they do help open one's eyes to what is important. American/christians assume they have a soul and therefore a place waiting for them in heaven. They believe they are exempt from putting in the effort to accumulate knowledge. I'm putting together an explanation of the soul and The Psychology of Ecstasy will help me do that, so thank you.
I'm not sure I understand euphoria being the 'germ of all art and true science'. Does that mean artists and scientists do what they do for the reward of euphoria? The pursuit of euphoria is what motivates many extreme athletes, extremely religious people and Opiate abusers. To me euphoria is a temporary, physical, extremely heightened state that cannot be sustained. I believe one can be truly happy with oneself without ever experiencing euphoria. Those few euphoric moments we have in a lifetime are to be cherished, but it may not be the best thing to try and keep recapturing the feeling.
