Prime Minister Narendra Modi said on Tuesday -- a day ahead of the third phase of polling in Bihar -- the ongoing election will decide the state's future.
Addressing an election rally in Sitamarhi district, Modi called upon the electorate to think carefully and vote.
"You have to decide who to trust for your future. If there is anything that can change your future, it is development," he said.
Modi said the solution to all problems in Bihar was not Modi, but development. He reiterated that India will develop only if Bihar develops.
"On the one hand there is development, and on the other there is opportunism," the Bharatiya Janata Party (BJP) leader said, referring to his opponents.
"It is not about winning or losing, it is about defining Bihar's future," said Modi, underlining the need to provide electricity, water, roads, education, jobs and healthcare in the state.
"I had promised to give a package of Rs. 50, 000 crore (to Bihar). After taking power, we gave Rs. 1.65 lakh crore. "We want to provide electricity to each house in Bihar. We have already decided to give Rs. 250-300 crore to each district."
He accused his rivals, including Chief Minister Nitish Kumar, of making baseless allegations against the BJP-led alliance.
The PM attacked Nitish Kumar and RJD chief Lalu Prasad, saying Bihar cannot be taken back to the 18th century.
"Can mantra or tantra help political parties escape their misdeeds?" Modi asked in an obvious reference to Nitish Kumar's meeting with a tantrik.
The five-phase Bihar election began on 12 October and will end on 5 November. The counting of votes will take place on 8 November.
