Query: the Celestine Prophecy is very challenging spiritually !

I found the Celetine Prophesy very challenging both spiritually and intellectually ! The author hit me square "between the eyes" the question of why I am on this Earth while painting a story against a vivid backdrop of adventure from the rain forests of South America to the peaks of the Andes ! The visual imagery is spectacular but the awakening of all of the senses of smell, touch, hearing is surpassed by the awakening of one's spiritual conciousness ! A must read ! ! !to my fellow adventurers . . . fond readings !Frank Ko
