Ken Wilber is one of my favourite western philosophers who has integrated the milestones of all disciplines of science, and eastern philosophy into a roadmap for us modern seekers. This book was particularly important for me in giving a link between Buddhist theories of interdependance and rational, empirical scientific observation.

It discusses at length the actual concept of a Boundary, what it means, and why it doesn't so much separate as join, and this insight alone is worth exploring the book for.

The book will take you into an indepth look at where you believe the boundary of your own existence lies. Is it your mind? Your body? something else entirely?

Wilber can be rather hard to stay with at times, needing a big effort of engagement intellectually, but there are always rewards for the heart if you stick with him.

I would like to get to grips with his massive extended version of this book - "Sex, Ecology, Spirituality" at some stage. When I'm feeling really daring!
