On Thursday, the president invited him along with his family to Rashtrapati Bhavan - a rare honour the 55-year-old says he will not forget for the rest of his life.

'It was a great experience. I was overwhelmed by the fact that the president had invited me and given me such a great honour. Since she also invited my family, I went there with my wife and two children,' Rao said.

Talking about their interaction, Rao told IANS: 'She appreciated my work, saying that I am a brilliant writer and that my work was excellent'.

He also presented copies of his books to the president.

'I sell my books in schools and colleges everyday. But the love for Hindi which is our national language has gone down among students,' he said.

Rao is now working on his next novel, 'Abhivyakti' which is based on social causes.

'My last book, 'Ram Das' sold 222 copies. Because of the big demand I am going to publish it again,' he said.
