I'm sure that we can all agree that no intelligent, conscious man or woman would ever intentionally hurt him or herself. It is important that we are in agreement about this precept. No one would choose to ache. Yet the fact remains that all of us do hurt ourselves every day with bursts of anger or fits of depression or anxiety. Even at the simplest level there can be no doubt: fear and worry take an immeasurable toll on our health and well-being.
However, there is real intelligence. An inwardly awake person would never intentionally hurt himself. Self-observation is the key to developing this higher order of awareness; it is how we learn to become inwardly vigilant to our own thoughts and feelings, even as they pass through us. When we can observe ourselves in this new way our higher nature naturally prevails over any troubling thoughts or feelings that want to drag us down into their lower world.
