After spending many ears as a "seeker" I think Ken Wilber's works clarified a lot of the confusion I was having about what I "saw" in the "spiritual world".
One aspect of it was how can a Muslim Suicide bomber, the Pope, a "New Age Hippy", and the Dali Lama all be "inspired" by spirituality?
A good introduction to Ken's thought is this article on belief net:
Which Level of God Do You Believe In?
To delve further into Ken's works, check out all the A/V on the
intergralnaked.org website.
Also, I highly recommend the talks from Genpo Roshi and all the teachers at the Kanzeon Zen Center which are available at:
Zen Eye.
Finally I put together my own "cliff notes" for anyone interested in exploring Buddhism:
