Congress President Sonia Gandhi, who renounced prime ministership after 2004 polls, on Sunday said India has taught her that politics is not just the art of possible, it can also be the ''art of the impossible.'' Delivering a lecture on ''Living Politics: What India has Taught Me'' at the Nexus Institute here, Italian-born Gandhi, said, ''the plain fact is that power for itself has never held any attraction for me.'' ''My aim in politics has always been to do whatever I can in my own way to defend the secular democratic foundation of our country and to address the concerns and aspirations of the many whose voice often remains unheard,'' she said. The Institute is a leading Dutch think-tank, which organises lectures and conferences on political, cultural and philosophical topics. Nobel laureate Amartya Sen has delivered a lecture there. Prime Minister of the Netherlands Jan Peter Balkenende hosted a dinner in honour of Gandhi, who is visiting the country at the invitation of the Institute.
