Moorakh Hriday Na Chet is a refutation book written by Nigrahacharya Shri Bhagavatananda Guru. In opposition to Tulasi-Pithadhishwar Rambhadracharya, describing the Uttarkand of Ramayana as projected alteration, at first Nigrahacharya had written a book titled " Uttara Kanda Prasanga Evam Samnyasadhikar Vimarsha ", to which Rambhadracharya has answered by writing the book "Sita Nirvasan aur Shambuk vadh nahi". In his counter-refutation, Nigrahacharya defeated Rambhadracharya by writing "Moorakh Hriday Na Chet" by the evidences in the written argument and proved the Uttarkand to be authentic and a real part of Ramayana.
