idol worship

we are aware that human brains can't comprehend anything which does not have a shape or picture.  You can't imagine a vaccum or what a vaccum is?  Humans have thus a qualified mind which fact can't be disputed.  In this scenario, how can a human being visualise God without a form?  It is simply impossible.

That is why, our ancestors have held the view that the idol worship in various forms to signify various aspects of God is a means by which a human can understand who and what is God?  And this will ultimately lead one to  realise oneness of God, Who doesn't have a shape but is only light of complete knowledge.

When God is one, then why should we have different forms of His?  It is simple.  A man or a woman plays so many roles in his/her life even though he/she is one.  For example, a woman is a mother to her daughter/son, wife to her husband, a daughter to her parents and so on.  After all, a human being takes so many roles.  God has so many aspects and attributes to him.  And so, our ancestors have devised various forms of God to understand God's true nature.

I think, we are indebted to our ancestors for devising methods to realise God.  And so,idol worship is absolutely correct.
