I have long set zen aside as being too zany and illogical for me. But I relate to its Mahayana components and similarities with the Kagyu and Nyigma schools of TB and connection to Taoism. Anyway, I've been thinking I should spend some time and investigate it more thoroughly and honestly and I came across Integral Zen, which has a strong connection to Ken Wilbur and his Integral Philosophy. Anyway, there is a lot there on the surface that I am relating to, but there is also something there (which may be my own projection) that gives me pause. Does anyone have any knowledge of this tradition or Ken Wilbur?
