Good 2

Dissolution of evil in mind is different from fighting evil in the material reality.
The basic rule for mind is positive. It is doing good and getting good. It is a principle of knowledge and relaxation. The good is in the idea, not in the power of the execution.
On the material level, good ideas which are not executed powerfully have no impact.
On the mind level, excess of power is a problem. If you use a PC or Mac, you just break the keyboard if you use too much force.
The strategy for dissolving evil on mind level is just doing good. The presence of evil is a rich source for doing good.
There might be problems if the brain is drugged or manipulated in other ways, if there is secrecy, lies, irrational behaviour and the like, but eventually these aspects are drawn into the light and dissolved also.
