The Times of India report says:
"And how was this dating done? "Considerable research" and a software procured for around Rs 7,000 from the US were the keys apparently. "Planetary information" from the Rig Veda, Ramayana and Mahabharata was used to find the exact dates, said Saroj Bala, director of the institute. Hosted at Delhi's Lalit Kala Akademi, the institute's 'findings' have been submitted to the Union culture ministry."
Would it not be in fitness of things if Saroj Bala published her research in some standard research journal so that historians and other scientists including social scientists could assess her valuable research before submitting it to the culture ministry ! If she has done so already she must share the name of publication so that others could carry forward the 'good break' given by her to epic chronology.
