Taking extremes is bad. The word “wasat” (literally means middle) is used in the Quraan and the tradition of Allah’s messenger to describe the attribute of Muslims, their actions, and their viewpoints. It is basically a middle point between two extremes both of which are bad.
A person whose courage is so intense and not mixed with wisdom isan extremest. This courage is going to bring about trouble. On the other hand, a person with mild courage is basically a coward. The middle, having courage which is guided by wisdom, is the moderate attitude.
People might think that stretching oneself to the extreme is difficult. I think that is absolutely wrong. Being moderate is more difficult. Knowing what the moderate point is and trying to reach it require more effort and more time. It is like a hill whose top is this “high” moderate point and both ends are the extremes. One needs to climb the hill to reach moderation. Also, staying moderate by maintaning your position always on the top needs effort.
There is a price of being moderate. You will have to be able to overcome the gravity from both sides to maintain your position. You also need to overcome people shouting from “both” sides telling you that you are wrong and you ought to come down. On the other hand, people of extremes are safe and relaxed in each side of the hill.
