The senior leader also sought to know what welfare activities the actor had done for the people of the state during the 2004 tsunami tragedy and the devastating floods of 2015.
"Politics is a bed of thorns. It should not be underestimated. Let him see the kind of difficulties in it by entering it. He should not pretend that he is entering politics," Jayakumar told reporters here.
"Have you (Haasan) done any welfare for the people through your fan clubs during tsunami or the floods," he asked.
Instead of acting, Haasan was "just uttering words" and the people of the state will realise it, the Minister said, and suggested the star should make his political plunge by January, apparently in 2018.
Ever since Kamal Haasan had made allegations of corruption in the government, he has been targeted by the ruling dispensation, with Chief Minister K Palaniswami himself asking the national award winning actor to take the political plunge to get proper response.
Local Administration Minister SP Velumani had sought proof for Haasan's allegations and had asked if the actor was ready to furnish tax details of his films.
The opposition including DMK have backed Haasan and urged the government to respond to his charges of corruption rather than targeting him.
