Be very careful that you do not unconsciously assume that nervous tension is power. This is vital. Watch yourself the next time you work toward some goal. Look very closely to discover tense feelings and nervous thoughts whirling around inside. Do not let them deceive you into assuming that they are creative forces; they are not. They are thieves of genuine powers. As always, your awareness of their thievery is your first fine step toward casting them out.
