Addressing a huge youth rally in the city, the Gujarat chief minister said, "If I speak the truth, all the ministers of the Delhi government get unhappy, they feel bad and get dejected."
"There is a reason for it. Nobody has challenged them for the last 60 years. They are feeling how can a tea-seller challenge such a big sultanate which has ruled the country uninterrupted for many years," he said.
"They are flabbergasted and remain in search of opportunities to hit Modi... My Congress strongmen, what more can you do, you can throw muck, you can let CBI try to nail me, you can take me to courts...," Modi said.
"But I am here to serve this nation births after births, If I don't get chance in this birth, I will come again in the next birth to serve the people of the country."
"I have not left my house for any post or fame. To acquire, to be something is not my goal...," he said.
Modi also quoted a few poems in his speech, which centred around the theme that he was ready to sacrifice himself for the country.
Union Finance Minister P Chidambaram had recently accused Modi of having a self-centred "I, me, and mine" attitude.
Modi said it was the responsibility of those in power to think about the youth, give them skill development training, jobs, and turn the demographic dividend into advantage, or else the large population of the youth will turn out to be a disadvantage.
"In the last year's budget, the central government had claimed it will give skill training to 10 lakh youths and had made a provision of Rs 1,000 crore. In reality they have given training to just 18,352 youths in the last year," he claimed.
"This is five per cent work done. At this rate the Congress government will be able to complete the target in the next 20 years," he said.
"These elections are different from all the earlier elections, as this time people have decided the result in advance," Modi said.
