General Meaning: Personal resolution points to a breakthrough, but decisive action is required. As long as you diligently hold your ground and ward off negative tendencies and influences, the good will prevail.
The persistence of negativity, which is that which opposes the good, is a constant in human affairs. Just when it is thought to have been eradicated, up it will pop again, sprouting through some crack in the pavement of civilized society. Evil need not take dramatic or extravagant forms, such as those exhibited in Nazi Germany. Garden-variety lies and deceit are much more common and persistent, but should be rooted out just as diligently. One must be determined to not accidentally feed negativity — either in one’s social or professional life, or in one’s own soul. In either case, definite rules must be followed for the struggle to succeed.
The first rule: do not compromise with evil. Destructive or exploitive actions must be identified openly for what they are, and discredited. The second: one cannot successfully resist negativity on its own terms. New, positive alternatives that lead away from the source of the problem are generally more successful, and appropriate than trying to counter negativity with raw power. The third rule: the means used to counter negativity must be consistent with the end to be achieved. One cannot stop the spreading of lies by spreading more of them.
