The Magician should devise for himself a definite technique for destroying "evil." The essence of such a practice will consist in training the mind and the body to confront things which case fear, pain, disgust, shame and the like. He must learn to endure them, then to become indifferent to them, then to become indifferent to them, then to analyze them until they give pleasure and instruction, and finally to appreciate them for their own sake, as aspects of Truth. When this has been done, he should abandon them, if they are really harmful in relation to health and comfort.
