Stand guard at the door of your mind.
Some brains are easy to hack into, and other brains are nearly impossible to hack into because they are so complex.
Some computers have security software that make it impossible to hack into, and it's the same with brains - some malfunction, and some, you can't hack into them at all.

Vigilantly guard your mind against erroneous and destructive thought as you would guard your house against burglars and assassins.

Arguments which penetrate into the magic aura are not dealt with rationally but by a specific type of pseudo-reasoning. Absurdities and contradictions are made acceptable by specious rationalizations.
