Simply following what your forefathers have prescribed and doing it without questioning would account to following the herd. Ask them why they did that or for what reason those rituals and rites were performed. You will be amazed at their ignorance. They will offer some mumbo jumbo explanations for doing that. You should do those till your questioning hasn’t started but once you are questioning these weird activities, refrain from doing those till you are thoroughly convinced about them. Perform them only if you believe in them. Faith after ascertaining the truth will lead you to perfect answers. Then you will never delude the future generation.
