Furthermore, Oak cites several documents suggesting that the Taj Mahal predates Shah Jahan's era:
Professor Marvin Miller of New York took samples from the riverside doorway of the Taj. Carbon dating tests revealed that the door was 300 years older than Shah Jahan.
European traveller Johan Albert Mandelslo, who visited Agra in 1638 (only seven years after Mumtaz's death), describes the life of the city in his memoirs, but makes no reference to the Taj Mahal being built.
Many rooms in the Taj Mahal have remained sealed since Shah Jahan's time, and are still inaccessible to the public. Oak asserts they contain a headless statue of Shiva and other objects commonly used for worship rituals in Hindu temples.
Fearing political backlash, Indira Gandhi's government tried to have Oak's book withdrawn from the bookstores, and threatened the Indian publisher of the first edition with dire consequences.
The only way to really validate or discredit Oak's research is to open the sealed rooms of the Taj Mahal, and allow experts to investigate.
