"And now what methods may be employed to safeguard the worker in the field of the world? What can be done to ensure his safety in the present strife, and in the greater strife of the coming centuries? 1. A realisation that purity of all the vehicles is the prime essential. If a Dark Brother gains control over any man, it but shows that that man has in his life some weak spot.... 2. The elimination of all fear. The forces of evolution vibrate more rapidly than those of involution, and in this fact lies a recognisable security. Fear causes weakness; weakness causes a disintegration; the weak spot breaks and a gap appears, and through that gap evil force may enter.... 3. A standing firm and unmoved, no matter what occurs. Your feet may be bathed in the mud of earth, but your head may be bathed in the sunshine of the higher regions... 4. A recognition of the use of common-sense, and the application of this common-sense to the matter in hand. Sleep much, and in sleeping, learn to render the body positive; keep busy on the emotional plane, and achieve the inner calm. Do naught to overtire the body physical, and play whenever possible. In hours of relaxation comes the adjustment that obviates later tension."
