I have made another connection between Castaneda and Pullman! Castaneda spends a long time discussing the idea of the Tonal and the Nagual, the Tonal it seems is what Pullman describes as a Daemon. You may laugh and say that Philip Pullman has nothing to say, he's a childrens book author. I would say you were wrong, he has a definate philosophy that ties in with and sits nicely alongside Castaneda. Castaneda says the following about the tonal:

I would say then that the tonal is a guardian that protects something priceless, our very being. Therefore, an inherent quality of the tonal is to be cagey and jealous of its doings. And since its doings are by far the most important part of our lives, it is no wonder that it eventually changes, in every one of us, from a guardian into a guard. A guardian is broad-minded and understanding. A guard, on the other hand, is a vigilante, narrow-minded and most of the time despotic.

This relates almost exactly to Pullmans daemons, and how their multiform nature becomes fixed with age and once they have settled on a form it will never change. Castaneda Says that you can never rid yourself of the tonal or you will die, and the same is true of the Daemons.

They do differ from this point forward however. Castaneda wants you to minimise your Tonal and live in the Nagual, Pullman does not go this far, and the Daemon is to be always a part of a life according to him. So who is right, the childrens author, or the mysterious man from Mexico?

Pullman doesn't have the rich layering of roles that Castaneda has in his philosophy, he describes only the life of an ordinary man. Castanedas philosophy goes beyond that of the ordinary man, and into that of the Hunter, Warrior, and Sorcerer.

Both men it seems are correct, there is no dispute in their philosophy, it's just that one goes a lot further than the other.
