I can somewhat understand the fails part, thanks Michael, but looking how sorcery is so energetic, that energy is everything, is it a worthwhile vestment to focus on change, when the warrior says you cant change anything about yourself? Most of the lit on this, is about doing away with the self, leaning on the energy body, realizing we're magical beings, not just physical ones. It seems to me, then, the quote to be quite odd. Change is going on all the time, and carlos certainly changed under don juan. How could one not change under such conditions?
It could be meaning the witness never changes, maybe thats what was meant, like the witness in buddhism. I am not sure.
