"Some people are criticising saying the government did not make ample preparation. I think that is not the issue that the government did not make ample preparation. I think the pain of such people is that the government did not give a chance to make any preparation," he said at a book launch function .
"If these people had got 72 hours to make their preparation then they would have lavished praise that there is no one like Modi," he stressed.
Modi said the country is fighting a big battle against corruption and black money and the ordinary citizen is the "soldier" in this fight.
Noting that India's name features prominently in global corruption surveys which is not something to be proud of, he said, some decisions have to be taken in the interest of the nation.
Modi sought the cooperation of public in making the "war
on corruption" a success and said the wrongdoings of some are being caught only with the support of common people who are coming forward with concrete information about hoarders.
Lauding people's role, he said, "They have not only braved hardships, but have also powerfully responded to those limited few who have been trying to mislead them."
"It was my earnest wish that the ongoing campaign against corruption and black money, including the realm of political parties and political funding, be discussed extensively in the Parliament. Had the House functioned properly, there would have been comprehensive deliberation.
Giving a push to his plea for cashless economy, Modi also launched two new schemes for traders and customers that will dole out 15,000 prizes every day to those making digital transactions.
"So many rumours were spread, even the fight against corruption and black money was sought to be tainted with shades of communalism," he lamented.
"But I have seen that despite rampant rumour mongering, citizens have stood firm with their faith intact," the PM said.
Terming this "war" against corruption as "an extraordinary one", he said the forces involved in "this murky enterprise of perfidy and corruption" have to be defeated as they are devising new tactics to thwart government's efforts every day.
Lauding the people for exposing the wrong-doings of some who are devising "newer wily ways and means" to counter the fight against corruption, the Prime Minister sought more public support.
