The Hidden Hindu Book 1

Prithvi, a twenty-one-year-old, is searching for a mysterious middle-aged aghori (Shiva devotee), Om Shastri, who was traced more than 200 years ago before he was captured and transported to a high-tech facility on an isolated Indian island. When the aghori was drugged and hypnotized for interrogation by a team of specialists, he claimed to have witnessed all four yugas (the epochs in Hinduism) and even participated in both Ramayana and Mahabharata.
