No writings in the physical world are infallible, since writings are only as effective as our ability to understand them. Since we are asleep and deeply confused, we lack the ability to see what the writings are truly saying. Instead, we only hear how our personality and ego "interpret" what we read.

Someone who is totally awakened can acquire enormous information from a single letter or word, while even if we memorize entire libraries we remain ignorant.

That said, there are many beautiful writings that can stimulate us to change, and Samael Aun Weor's writings count among them.
