Silent knowledge" is nothing but direct contact with "intent. - Carlos Castañeda

When man fell to his knees he became the asshole he is today.

Every time a man sets himself to learn, he has to labor as hard as anyone can, and the limits of his learning are determined by his own nature. Therefore, there is no point in talking about knowledge. Fear of knowledge is natural; all of us experience it, and there is nothing we can do about it. But no matter how frightening learning is, it is more terrible to think of a man without knowledge.

Nothing can temper the spirit of a warrior as much as the challenge of dealing with impossible people in positions of power. Only under those conditions can warriors acquire the sobriety and serenity to withstand the pressure of the unknowable.
