The senior BJP leader also said AAP had an advantage in the elections as it started preparations about a year ago.
"It is a matter of concern and consideration for the BJP (chinta aur chintan vishay)," he said on the sidelines of the event to present Dr. Ambedkar National Merit Awards to meritorious students here.
BJP suffered a humiliating defeat in the just-concluded elections for the Delhi assembly, securing a paltry three seats, while AAP registered a landslide victory winning 67 of the total 70 seats.
Congratulating Kejriwal on his victory, the Union Minister expressed hope that the AAP would fulfil those promises that the party has made to the people.
Gehlot further said that BJP has not lost the battle ground, saying the party had won 282 Lok Sabha seats starting from just two seats.
"We are not disappointed... We have lost the battle but not the battle ground. We had won two Lok Sabha seats in 1984, but raised the numbers to 282," he noted.
