Brahmaśirastra-pratisaṃhāra — Retraction and redirection of the supreme weapon
Sauptika Parva, Adhyāya 15
विसृष्टस्य रणे तस्य परमास्त्रस्य संग्रहे । अशक्तः पाण्डवादन्य: साक्षादपि शतक्रतु:
visṛṣṭasya raṇe tasya paramāstrasya saṅgrahe | aśaktaḥ pāṇḍavād anyaḥ sākṣād api śatakratuḥ ||
毗湿摩波耶那说道：当那至上的神矢在战场上被放出之后，般度诸子之中再无人有能力将其收回并重新摄入——即便是“百祭主”释迦罗图（因陀罗）也做不到。此段强调神兵所伴随的沉重责任：一旦出手，召回之难几近不可思议，唯有兼具技艺与克制的宗师，方能止住其毁灭之势。

The verse highlights that the use of supreme weapons demands exceptional restraint: releasing a divine missile is easy compared to recalling it, and true mastery lies in the ability to control and withdraw destructive power.
Vaiśampāyana remarks that once the supreme weapon was discharged in battle, recalling it was beyond everyone’s capacity—so difficult that even Indra is said to be unable—implying that only Arjuna had the skill to withdraw it after release.
