Sources said Shah asked the state leaders to work to ensure that government schemes reach their target beneficiaries.
BJP ministers in the state government should meet the public at the party's office in Patna on Mondays and Tuesdays, he is learnt to have told them.
"The meeting focussed on issues related to the party organisation as well as the government. Shah also stressed on the need to strengthen the party further in the state," Shah said.
The BJP had won 22 and its allies nine seats in Bihar in the 2014 Lok Sabha polls in which the Kumar-led JD(U) won only two out of total 40 seats.
Till 2013, when the JD(U) broke ties with the BJP, the former was the senior partner in the Lok Sabha as well the Assembly.
Though the BJP has not commented on the matter officially, sources have said it will seek to contest more seats than the JD(U) in the next Lok Sabha polls due to its massive victory in the last election.
