I'm still working on Integral Psychology by Ken Wilber, I thought this was interesting coming from a proponent of meditation:
Because the traditional Great Chain theorists had a poor understanding of the early, infantile, prerational stages of human development, they likewise failed to grasp the types of psychopathologies that often stem from complications at these early stages. In particular, psychosis, borderline, and neurotic diseases often stem from problems at the early fulcrums of self-development, and can best be approached with an understanding of their developmental dimensions. Meditation--which is a way to carry development forward into the transpersonal--will not, as a rule, cure these prepersonal lesions (as hosts of American practitioners found out the hard way).
