Divide By Zero said:I'm not sure we can use much of Castaneda reliably.
There is a similar situation as in any other (religion, articles, historical data...). There are good and bad sides, accuracy and inaccuracy. The basic question is whether you can benefit from something or not. One can read the fairy tale and use it for inspiration to achieve something.
When it comes to magic or spiritual significance, a person who has reached an appropriate level of knowledge will recognize useful (truth). It does not go as much from 0 to 5 but is more like from 5 to 6. You have to have 5 to get 6. You can upgrade a bit. Cannot be that one who does not know anything about subject, read Castaneda's book and suddenly knows a lot. A beginner will only feel confused or focus on funny parts (Some will be reduced to devouring hallucinogenic mushrooms.)
In a way it is good that there are opposing attitudes, that religion is a lie/true, that Earth is a flat panel/ball, that Castaneda is lying/saying true because it helps people who want or not want to believe something. There is this balance of opposing information. Are pyramids made of people or inhumane forces? A person can believe what he wants, without pressure. Because this is a middle-level planet, it's not very polarized to good or evil, and people are left to decide on their own. If your heart feels calmer when you read that Castaneda is unreliable, this means that you can not(yet) / do not want(yet) to benefit from it. And that's fine. There are various methods for different people.
