He, however, appealed to RJD workers to be prepared to sacrifice as the party would field candidates only on 100 seats out of a total of 243.
"Its not a free time like in the past when lantern (RJD election symbol) fought on all 243 seats. In the changed context of this elections, the party has got 100 seats on which we have to select candidates," Prasad told reporters after a meeting of RJD Central Parliamentary Board.
Earlier, the Central Parliamentary Board adopted a resolution passed by state party Parliamentary board authorising Lalu Prasad to select candidates and sort out issues with allies.
Prasad, however, asked state RJD President Ramchandra Purbe as well party Vice President Raghubansh Prasad Singh to make necessary correction and authorise Central Parliamentary Board and not him for finalising name of candidates.
Meanwhile, media reports suggest JD(U) President Sharad Yadav, who was camping in Patna for past four days, left for Delhi this afternoon after failing to defend seats of some close confidante JD(U) MLAs from going into RJD hands.
"Within this 100 seats some old friends would go while some new ones would come," the RJD chief said in a bid to make leaders aware of changed political scenario in the October-November poll.
He advised party leaders to make workers understand that "the fight this time is big as we have to stop BJP from coming to power...Be prepared to sacrifice personal greeds."
Congress party and its leaders have made sacrifice for the country, he said.
