Atal Behari Vajpayee rings loud and clear holding the rural audience spellbound: "Andhera Chhatega, sooraj niklega, kamal khilega (the darkness will disappear, the sun will rise, the lotus will bloom)".
The former PM is too ill to be present but his virtual presence has been felt in 110 of Madhya Pradesh's 230 constituencies - thanks to the party's hi-tech campaign in the state.
"There are four LED (light emitting diode) vans constantly touring and showing rural people 30-minute films to convince them to vote for the party," said Prabhat Jha, who is looking after the BJP's campaign in the state.
The vans, rented at Rs 50,000 a day, have a hydraulic system that makes a giant screen rise up through the roof. The screen, very different from the usual two-dimensional screen, comprises small bulbs which light up to take on the shape of Vajpayee - or any other shape programmed.
Beginning with excerpts from Vajpaee's speeches, the film shows clippings of the speeches L.K. Advani, Rajnath Singh and state Chief Minister Shivraj Singh Chouhan.
"Such a screen is being used for the first time in MP. It is generally used on scoreboards to show cricket scores in international matches. Its speciality is that one can see images on it clearly even in the daytime," said Sudhir Sharma, who is helping coordinate the campaign.
The Congress campaign pales in comparison. It initially had some vans touring the state at night using an old fashioned projector but they are not being used now. "Candidates themselves are visiting all parts of their constituencies, so these are not needed," said Congress state general secretary Rajiv Singh.
