Mbh 14.12.1b

Nor is it proper, O son of Pritha, and conqueror of thy foes, that thou shouldst recall the incident of Kichaka's kicking Draupadi, during the period of thy exile passed in absolute concealment, nor the incidents of the fight which took place between thyself and Drona and Bhishma. The time has now arrived, when thou must fight the battle which each must fight single-handed with his mind. Therefore, O chief of Bharata's race, thou must now prepare to carry the struggle against thy mind, and by dint of abstraction and the merit of thine own Karma, thou must reach the other side of (overcome) the mysterious and unintelligible (mind). In this war there will be no need for any missiles, nor for friends, nor attendants. The battle which is to be fought alone and single-handed has now arrived for thee. And if vanquished in this struggle, thou shalt find thyself in the most wretched plight, and O son of Kunti, knowing this, and acting accordingly, shalt thou attain success. And knowing this wisdom and the destiny of all creatures, and following the conduct of thy ancestors, do thou duly administer thy kingdom."'"
