google or youtube alan watts, nassim haramein, dan winter, eckhart toll, terence mckenna, david wilcock for starters and see what you think. look through the archives on this website, in the appropriate section you wish to learn about, of course. there are many more topics, most of which can be found simply by looking at the ones you have access to and doing your own research based off of the info you find.
"how far down the rabbit hole are you willing to go?" is the real question...
thanks!
