I am skeptical of this as it gets applied in consumerist Western societies. It's all too easy to become the same ego you were before, only now with a spiritual varnish. In my observation, there is a lot of rationalization around this. When you have no roots in a tradition, it's easy to twist it to be whatever you feel it should be. Typically it turns into an accoutrement. George Westerholm brilliantly summarized this as "Does Taoism make me look fat?"
