Gandhi was speaking at an event organised by the Congress here on the eve of 125th birth anniversary commemoration of Nehru.
"There is a concerted attempt to destroy his (Nehru's) legacy and ideology. Some forces are at work and we have to fight them," Gandhi said without naming the ruling Bharatiya Janata Party.
"We should remain committed to fight those who want to destroy the liberal and progressive edifice of India," she said.
Speaking in Hindi, Gandhi said that the Congress has had a history of 129 years and the party would continue to exist despite difficulties.
"We have faced many challenges and learned from them as we had learned to face challenges from our leaders. Had Pandit Nehru been here, he would have asked us to go back to people and connect with them and strengthen the organisation," Gandhi said.
"Nehruji's ideologies are not just a part of history, they inspire us even today and undoubtedly they will inspire generations to come."
