I got this link via Vikipedia. This was a theory put forth by Mr.P.N.Oak who claimed that Taj Mahal is actually a Hindu temple called Tejo-Mahalaya. To my startling suprize, the top the Dome called Finalle is shaped like a Trishul. It also has leaves with a coconut in a vessel which is a typical Hindu custom. This theory was put way before the Sangh Parivar became popular. The pseudo-secularists thrashed his theory in Supreme court out of fear of hurting Muslim sentiments.
Note that this is a theory. Not necessarily a fact. Whether it is a fact or not is what we should debate. No abusive language from anyone please. Else I will not respond. Thanks.
