There are principal flaws in the Shia belief which is totally against what Islam was or claimed to offer initially. One thing that is stressed a lot in Qur'an is monotheism and the uniqueness of God and that he has created the world alongside with the rules to govern it. Superstition has been attacked from the first days of Islam and that ideology gave the new Moslems' minds the courage to get free from chaos and go to discover those rules. Now after so many years we are defying those early principles and the chaos is back in our minds and lives.
I am talking about Emam_e_Zamaan and Tavassol.
