It was a great gesture on his part to have called me his Guru, in my most popular and talked about biography 'Anything but Khamosh'. I'm very touched, but on a lighternote, I will say if I am his Guru, then he has become the real 'Guru Ghantal'. God Bless! The most popular superstar especially down South in particular and in Indian cinema in general has now taken the bold and beautiful decision to enter politics, better late than never. Hope, wish and pray that he lives up to the expectations of the people with his earnest sincerity, fairness and strong will. Lots of love to his wife, the real backbone, Latha and his family.
