Addresssing a rally in the mining state, the BJP's Prime Ministerial candidate allleged that India's first Prime Minister Jawaharlal Nehru had "mocked" at the demand for creation of separate state of Jharkhand.
He also hit out at the UPA government over alleged corruption in giving clearances for power projects and revived his "Jayanthi tax" barb to target former Environment Minister Jayanthi Natarajan.
"Yesterday Congress party released its manifesto. For any political party, its manifesto should be like the Gita, the Quran and the Bible and not some document to throw dust in people's eyes. Congress party made its manifesto a political tool and did not maintain its sactity," Modi said.
Interacting with the crowd, he asked them whether they will trust the words of Congress or its "false promises" made in the manifesto.
"They had made promises even in 2004 and 2009. They had said that they will bring down prices and will provide job to one member of each family. Whether they gave you the jobs" he asked.
Modi also chose the occasion to urge the Election Commission to frame some rule under which a party, which comes to power, should be asked after remaining in power about how many of the promises made in its manifesto were fulfilled.
Addressing a pre-dominantly tribal gathering, Modi accused Congress of ignoring the welfare of tribals.
"These Congress people had no idea that our tribals brothers and sisters also live in the country. A number of Congress governments came to power in last sixty years. Nehru became Prime Minister. But they never thought about creating a ministry for the welfare of tribals," he said.
He said that it was NDA's Prime Minister Atal Bihari Vajpayee, who created a dedicated ministry for tribals and earmarked a separate budget for them.
"A number of Congress governments came but they did not give power in your hands....Vajpayeeji gave us Jharkhand, he gave the right to us to decide how should it progress.... Nehruji had mocked at the demand for Jharkhand.
"Now that Jharkhand is in place, Congress is adopting all kinds of tactics (hathkanda) to capture power. They stand behind some one at one time and some other at the other time," the BJP leader said, alluding to the different allies Congress had chosen in the state in the last few years.
Currently, Congress is partnering an alliance government with JMM and RJD in the state. Earlier, it had tied up with Babulal Marandi's JVM (P) and had also supported independent Madhu Koda's government.
