Introduction to Integral Theory and Practice: IOS Basic and the AQAL Map - by Ken Wilber

This 40-page PDF document is a succinct and powerful introduction to the AQAL Integral Framework, as conceived of and articulated by Ken Wilber.

*Note: The essay was later expanded into the pocket-sized and beautifully illustrated book, The Integral Vision: A Very Brief Introduction to the Revolutionary Integral Approach to God, Life, the Universe, and Everything. Highly recommended!
