Discussion on occultation is a vast topic and traditions in this regard are many. what is necessary for us to know is the following:is there anyone to ask about the philosophy behind occultation and is there anyone who can say: since I do not know the reason behind occultation, I do not believe as you do in the existence of Mahdi and I further say: if as per what you say, Mahdi is the imam, then it is necessary for him to appear amongst the people and walk in the market-places!
