"Immense love showered by people of Vadnagar gives me new energy to serve the nation with more zeal, the PM added.
He also criticised the Congress-led UPA government's health policy and said it did not pay attention to increasing the number of seats in medical colleges.
"Till the time Prime Minister Atal Bihar Vajpayee's government was in power 15, 16, 17 years back, our country made its health policy. After that for the next 10 years, a government came that hated development," PM Modi said.
"Due to the rules formulated by the past governments, very few students were able to secure admission in the medical colleges. Thus, we have taken up the task of opening one medical college for (every) three to four Lok Sabha constituencies across the country," PM Modi said.
"Since we also need good professors for such colleges, we have also increased 6,000 seats in PG medical courses in the last one year. Though some people criticised the move, we remained firm because we understand that we will need good professors for producing good doctors," he said.
