I never knew that dating an historical event can be so easy until I read the book “When Did The Mahabharata War Happen? The Mystery of Arundhati” written by Nilesh Nilkanth Oak By discrediting a cultural symbol of our society and destabilising the foundation of time keeping, Nilesh Oak’s research throws a disturbing and a serious challenge to the very basis of the Hindu society which is still functioning on the formulations given by the Vedic sages of yore. His research throws a challenge to the ingenuity of the Vedic sages for elevating Arundhati perennially to the celestial sphere much like Dhruva, the son of Uttanapada. Nilesh Nilkanth Oak’s research is based on a single verse of sage Vyasa told to Dhritarashtra just before the commencement of the Mahabharata war expressing a deviation in the usual appearance of the binary, Vasishtha and Arundhati (Mizar and Alcor) in the Ursa Major constellation identified as Saptarishi constellation by the Vedic society. The binary is always seen as though the star Arundhati is towing behind the star Vasishtha much like the real character Arundhati who always followed her husband Vasishtha. At the time of Mahabharata war, sage Vyasa has made a statement that Arundhati kept Vasishtha at her back – ‘pṛṣṭhataḥ kṛtaḥ’.
