A rally demanding "mother of the nation" status to cow will be held at Ramleela Ground in New Delhi on February 18, spiritual guru Gopal Mani said. The event planned by Bharatiya Gau Kranti Manch, will see participation of prominent leaders from political and social spheres, said Mani. "Unless cow is treated as mother and not as an animal, its slaughter will not stop in the country," Mani told reporters.
