Brahmaśirastra-pratisaṃhāra — Retraction and redirection of the supreme weapon
Sauptika Parva, Adhyāya 15
इत्युक्त्वा संजहारास्त्रं पुनरेवं धनंजय: । संहारो दुष्करस्तस्य देवैरपि हि संयुगे
ity uktvā saṃjahārāstraṃ punar evaṃ dhanaṃjayaḥ | saṃhāro duṣkaras tasya devair api hi saṃyuge ||
Vaiśampāyana dijo: Dicho esto, Dhanaṃjaya (Arjuna) retiró de nuevo el arma. En el fragor de la batalla, el acto de llamar de vuelta aquel proyectil divino era sumamente difícil—hasta para los dioses—y mostraba tanto el peligro de desatar tal poder como la rara disciplina necesaria para contenerlo una vez liberado.
वैशम्पायन उवाच
The verse underscores restraint and responsibility: the true mastery of power is not merely releasing a formidable weapon but being able to withdraw it, preventing needless destruction even amid war.
After making a statement (contextually, a decision or warning), Arjuna retracts the astra he had invoked. The narrator emphasizes that recalling such a weapon in the heat of combat is extraordinarily difficult—even for the gods—thereby magnifying Arjuna’s exceptional control.
