"This is cent per cent false. I never asked anyone to do so. I would get my head chopped if I ever asked anyone either in Satsang or in alone to do so...not even once since 1948," Singh said at his Aashram, nearly 40 kms from here.
"What else I can say beyond this," he added while replying to a reporter's question about the allegations of forced castration inside his Dera.
The Dera chief is in controversy after a former Dera follower, Hansraj Chauhan, approached the Punjab and Haryana High Court alleging that he along with some 400 saints of the Dera was castrated inside the ashram on the orders of Gurmeet Ram Rahim Singh.
On December 23, the court ordered a CBI probe in the matter and the agency would register an FIR.
In response to another question, the Dera chief said that saints or preachers are God gifted.
"Such personalities are sent by the God...they are God gifted and not created here," he said.
Regarding security in the Aashram, Singh said that he has done good works like inspiring five crore people to quit drinking and so those whose businesses have been affected do not like him. Hence he has to be under the security cover.
When asked about his acting, he said he never attended an acting school and that it was not "acting" but his real acts in the film.
The dera chief, who is going to hit the big screen next month with his film 'Messenger of God (MSG)', has already courted controversy with Sikh organisations, including Akal Takht, seeking a ban on it.
He has not only played the lead role in the movie but also produced it and sang songs. Gurmeet Ram Rahim is also facing trial in courts in connection with a case of murder of a journalist and sexual exploitation of his women disciples.
