ततः सुतं बलेजिंत्वा बाणं बाहुसहस्रिणम्
tataḥ sutaṃ bale jītvā bāṇaṃ bāhusahasriṇam
Then, having overcome the son by strength, he subdued Bāṇa, the lord famed for his thousand arms—showing that sheer might, when unchecked by dharma, can be brought under restraint by superior power and rightful order.
(भीष्म उवाच
Power and extraordinary might are not self-justifying; when they deviate from dharma, they can and should be checked—ideally by rightful authority that restores order rather than indulging in mere domination.
Bhīṣma narrates that after defeating a certain 'son' through superior strength, the victor also subdued Bāṇa, described as the thousand-armed one, indicating a decisive overcoming of formidable force.
