Integral philosopher Ken Wilber has launched a new venture hot on the heels of Integral Naked, this one dedicated to promoting and exploring his “post-metaphysical” approach to mysticism. Participants in the Integral Spiritual Center include noted Kabbalists Reb. Marc Gafni and Reb. Zalman Schachter-Shalomi, Patrick Sweeney (heir to the controversial Chogyam Trungpa Rinpoche), Putting on the Mind of Christ author Jim Marion, Father Thomas Keating, Omega founder Elizabeth Lesser, and many others.

To mark the occasion, the characteristically prolific Wilber has penned a 118-page paper introducing the post-metaphysical approach, which includes a critique of Spiral Dynamics and a theoretical preview of the sequel to his admittedly lame “postmodern” novel Boomeritis. Wilber does all of this amidst growing concerns of the perceived cult-like nature of his organization and deficiencies of his four-quadrant model.

One thing is for certain, you’ll be hearing a lot more from Wilber later this year.
