During his speech at the party headquarters, Modi told cheering supporters that the election has thrown up a mandate to build a new India. He also said and said the country will now have only two castes -- the poor and those who want to alleviate poverty.
"People are chanting Modi, Modi. But this is not a victory of Modi, it is the victory of people who are desperate for honesty in the system," Modi said.
Here Modi promised to devote "every moment" of his time and "every fibre" of his being for the people of India.
He said “I promise not to do anything for my self and I promise that every cell in my body is dedicated to the nation.”
Addressing the countrymen directly, Modi said he will not do anything with bad intention, even though, he added, he may at times commit a mistake on job.
"I will not do anything for myself," he said, signalling the noisy crowd to keep quiet and then added, "I will devote every moment of my time and every fibre of my being for my countrymen."
"Whenever you judge me, judge me on these three parameters. If I fall short on these, curse me. But I assure my countrymen that what I have said in public I will do my best to fulfil," he said.
Values and spirit of democracy and the Constitution enjoin his government to take everyone along as the country is run with consensus, he said.
"With bigger mandate, comes greater responsibility...I will not do anything with bad intention and and will do nothing for myself.” Modi said.
"While working, there can be mistakes but I will not anything with bad intention. I will not do anything for myself. Third thing, every second of my time, every part of body is only for the nation. You keep judging me on these three parameters and criticise me if I do not measure up. But I want to assure you that whatever I say publicly, I will work to implement it," he said.
"But the nation moves with consensus and democractic spirit." Modi said he will take his critics along with humility. "The people have filled the bag of this ascetic. I bow my head to 130 crore people of the country," he said.
