Penetration produces gradual and inconspicuous effects. It should be effected not by an act of violation but by influence that never lapses. Results of this kind are less striking to the eye than those won by surprise attack, but they are more enduring and more complete. If one would produce such effects, one must have a clearly defined goal, for only when the penetrating influence works always in the same direction can the object be attained.
Small strength can achieve its purpose only by subordinating itself to an eminent man who is capable of creating order.
