The True Story, Oak claims that the Taj Mahal was originally a Shiva temple and a Rajput palace named Tejo Mahalaya seized by Shah Jahan and adopted as a tomb. He argues that may be this temple was built by Indian King Jai Singh I. He says that Mahal is a word to describe a royal palace and not a tomb and after seizure by Shah Jahan, the name was changed to Taj Mahal.
The Taj, Oak says, is a “typical illustration of how all historic buildings and townships from Kashmir to Cape Comorin though of Hindu origin have been ascribed to this or that Muslim ruler or courtier”. He goes on to propose Hindu origins for the tombs of Humayun, Akbar and I’timād-ud-Daulah and “all historic buildings” in India as well as Vatican City, the Kaaba and Stonehenge.
