Instead of merely repeating certain sentences which you have read or been taught, think them over for yourself. If you were really the Real how could you become Illusion? If you were the True, how could you succeed in deceiving yourself so far as to become the False? If ignorance, error, and illusion can happen to the One Mind, then they are just as powerful as It.
