Q) Whats wrong with idol worship

An idol is a representation of the lord/god you wish to pray to - at least that is the nature of it. When worshipper looks at the idol and cannot comprehend the beyond, then the system gets faulted - thus the current 3033 gods in the Hindu culture - yet all is one and one is all - If all understand that and the mind looks beyond the actual representations, then you have one single almighty, supreme entity that permeates it's essence in everything and is everywhere. Where does the idol fit in this equation is for you to decipher.
