Well, things change - in fact, I would dare to suggest (timidly, from a position cowering behind the couch, being disdainfully sneered at by 2 out of our 4 cats - who are here for no good reason that I can see) that sometimes the greater intellectual rigour may be required to take something from the past and make it relevant to the present.
Well, there is an upside to all this neo business.
We can take advantage of several thousand years of evolution since the time of the Celts, and be gentler and more inclusive - without losing anything as a result, in my opinion.
Note 1 - if I am ill, I will use both "complementary", or "alternative" medicine, AND "conventional medicine. I know about the theory of germ causation of disease I work with that in my day job), but I also know about the importance of the psyche, and feeling good about oneself, and having good energies about oneself. In a sense, I blend old and new - I CANNOT use only old ways - to do so would not be true to myself.
