In his over 75-minute address after being elected the leader of the BJP-led National Democratic Alliance, Modi also stressed on the need to win over the trust of minorities, saying they were made to live in "fear" and "exploited" during elections for vote-bank politics, apparently a dig at the opposition parties.
"Unfortunately, minorities of this country have been kept in fear, used in elections. We have to end this cycle," Modi said, calling for winning the trust and confidence of minorities.
He accused the opposition parties of keeping the minorities confused and frightened, instead of working on the improvement of education and health among them.
Modi also said that poor people of this country have been cheated.
He invoked the spirit of 1857 struggle for freedom, saying all communities had then joined hands for independence and a similar movement should be started for good governance now.
"We stand for those who trusted us and also for those whose trust we have to win over," he said.
"We have worked for 'Sabka Saath, Sabka Vikas', now we have to strive for 'Sabka Vishwas'.
"The ones who vote for us, are a part of us. The ones who don't, are also a part of us," he said, stressing that no one must be left behind and there should be no discrimination.
Modi also gave several directions to the MPs, including to not give media statements merely for publicity and shun the "VIP culture".
With speculation rife over who will join his Council of Ministers, Modi said he was yet to go through details of all the NDA MPs and asked them to not trust media reports in this regard, adding they are aimed at creating confusion and often put out with "bad intentions".
Responsibilities will be given as per norms, he said.
Modi said elections often divide and create gulf but 2019 polls united people and society.
There was a pro-incumbency sentiment in this election and its result was a positive mandate, he said, adding that there is no better path than serving people when in power.
"We ran the government for poor people between 2014-19 and I can say the poor elected govt this time," he said.
He also called for the NDA to work with cohesion for the country's development and said his "naara" (slogan) for the alliance is "national ambition and regional aspirations".
The NDA has 353 MPs, including 303 of the BJP.
