Mental Strategies are the patterns of the mind that arise when a being is not living according to their correct Strategy and Authority — when the mind has been conditioned to believe it is the proper decision-making authority. The Not-Self Mind generates a set of recurring mental strategies: justifications, rationalizations, fears, and belief systems that feel compelling and logical but lead the vehicle away from its correct geometric path. Ra Uru Hu taught that there are specific Not-Self mental strategies associated with the undefined Centers — each undefined Center, when conditioned, generates a characteristic mental strategy (e.g., an undefined Head Center leads to the strategy of trying to answer questions that aren't yours; an undefined Will Center creates the strategy of trying to prove your worth). The core error of the Not-Self Mind is substituting mental reasoning for true Inner Authority — the result is decisions that take the vehicle out of its correct flow and into frustration, anger, bitterness, or disappointment.
