Over 25,000 thousand people have already gathered at Patna's Gandhi Maidan to attend his 'Hunkar Rally' , reports said.
Modi is expected to arrive at the venue at around 1 pm.
In order to make the rally a grand success, special traffic arrangements have been made at the two bridges across river Ganga leading to Patna.
The Bihar BJP has arranged 11 trains and 3000 buses to ferry people from all parts of the state to the rally, which is expected to be attended by all the 91 BJP legislators in Bihar.
A tea stall in the name of 'NaMo' has been set up to serve the attendees.
The Bihar BJP also plans to deliver to Modi a wishlist of things that he must promise to do if he becomes Prime Minister in 2014, including a special status for the state.
The rally comes just months after the Janata Dal (United) [JD-U] announced its decision to sever ties with the BJP, ending a 17-year-old alliance and drawing clearer battle lines ahead of national elections less than a year away.
