It seems the natural course of things that innovation and movement forward, eventually gets subsumed back into the very thing it originally was created in order to transcend. It's a typical cycle:On that latter point, I find it interesting that a spiritual teacher who was at odds with the religious hierarchy of his day, now has great institutions operating in his name and claiming his authority.
Spiritual movement becomes a religion, which then spawns a spiritual movement to break from its shackles, which then itself becomes a religion, which then spawns another new movement to overcome that, and so forth. Eventually, the leading edge, becomes the mainstream and loses its edge. The cake rises, then settles back down into the middle again.
