Chennai (PTI): A biography of Tamil superstar Rajnikanth, penned by noted author Gayathri, was released here on Thursday.

Veteran journalist Cho S Ramaswamy handed over the first copy of the book to the superstar's daughter Soundarya Rajnikanth.

Lauding Rajnikanth for his phenomenal success as an actor, Cho said Rajnikanth was a believer in spiritualism but he is not a spiritualist, an observer of politics but not a politician and an actor but not a showman.

"These qualities made him a great personality," he added.

If Rajnikanth decided to enter politics, as per wishes of the people of Tamil Nadu, he would provide an honest government in the state and would develop it as one of the finest states in the country, Cho said.

Former Director of CBI D Karthikeyan said Rajnikant was a pleasant man to move with and a man of humility.

Soundarya Rajnikanth said she was "proud to be the daughter of a great man".

Gayathri said Rajnikanth had narrated events of his life with great patience for the biography. "Youth have a lot to learn from him".

The 59-year-old actor entered the film world in 1975. His 'Sivaji the Boss' was a roaring success in 2007.
