"You should not compare how many terms but should do it on how much India has progressed in Modi's term," Modi told NDTV.
He said: "Modi will win thrice, five times or even seven times. I have the blessings of 140 crore people of India so this will go on."
Nehru served as India's first Prime Minister from 1947 till 1964.
Modi first won the general polls in 2014 to come to power in the country by removing the two-term old Congress-led UPA government.
He then went ahead to win another term in 2019.
If voted to power, Modi will return to power for a record third straight term, a rare event in Indian politics.
