Think before you act.

Once there lived an old priest in a small village. The old priest had a cat. The cat roamed around freely in the church. The old priest found the cat to be a distraction to the followers so he used a string to tie it up whenever there was a service. Then, the old priest died of old age, but people continued to tie his cat up whenever there was a service. Then, the cat died, but people found another cat and tied it up whenever there was a service. They thought that tying a cat up during a service is a ceremonial practice.

Sometimes, people just follow blindly without understanding the rationale behind an action. We ought to think before we act, else we may end up doing something that is totally unneccesary.
