There is growing recognition that when we brood and fuss and churn emotionally, body functions are apt to become disarranged and physical difficulties tend to develop. If we want to have better bodies and stay well, we need to avoid this pitfall.
We would all agree that one disruptive emotion is fear—fear of being sick and dying; fear concerning all that's dear to us; fear of losing face, being hurt, failing.
Other emotional extremes, however, are sometimes thought to have value. This is a dangerous assumption. Intemperance and passions, for instance, encourage dependencies—weakness, not strength. Grieving and lamenting may be selfishness, interfering with our work for mankind. Resentment is often no more than frustrated self-importance. And let's face it, the "righteous indignation" that may seem so proper on occasion is just a polite form of rage, debilitating, damaging.
