"Where there is anger, there is always pain underneath. Or when a dark mood comes upon you and you start getting into a negative mind-pattern and thinking how dreadful your life is, your thinking has become aligned with the pain-body, and you have become unconscious and vulnerable to the pain-body's attack. "Unconscious," the way that I use the word here, means to be identified with some mental or emotional pattern. It implies a complete absence of the watcher. p. 29-30"
