DIFFERENT ROADS TO EVIL
To better understand the concept of hippuch, we must first divide evil into its two major expressions. There is one manifestation of evil that results from the disregard of man's true goals. This takes place either when one is blind or apathetic to the Divine, or when one is pulled astray by temptations of lust or greed.
If one were to visualize service of God as traveling a road leading toward Godliness, then these types of yetzer hara, the evil inclination, could be pictured as either stopping in the middle of the road or simply going off the road at an angle. Never in this type of evil does the yetzer hara present itself as an alternative to truth -- but in the guise of a more comfortable, appealing lifestyle. Its power lies primarily in blocking man's vision entirely, or at least obfuscating the goal at the end of the road.
But there is a second form of evil, far more pernicious than the first. That is when evil presents itself as an alternative route to Godliness or poses as the Divine itself. No longer is it a question of straying from the road or becoming sidetracked; rather, it is a total reversal of the direction in which man is to be headed. Under this general rubric, we could include idolatry, kishuf (witchcraft), and perhaps extreme cases of ga'avah (self-aggrandizement).
If we wish to visualize it in terms of the road to Godliness, then this would be represented by an arrow pointing in the opposite direction, as if someone had lit a light at the wrong end of the road, beckoning the traveler to "progress" toward it.
