According to local media reports, Hariprasad, in- charge of Congress affairs in Chhattisgarh, has accused RSS of creating "dispute" between religions.
Speaking at a two-day training camp of Congress workers in tribal-dominated Sarguja district of Chhattisgarh, he reportedly said the "Sangh Parivar can go to any extent to grab power".
State BJP President Ramsevak Paikra today described Hariprasad's remark as "irresponsible" and "undignified".
Paikra said Hariprasad has "lost his mental balance and he needs to visit a psychiatrist".
Congress leaders who have sympathy for terrorists and Naxals cannot tolerate nationalists, the BJP leader said.
