तस्मात् प्राणान् धारयिष्ये मुमूर्षुरुदगायने । यश्न दत्तो वरो महां पित्रा तेन महात्मना
tasmāt prāṇān dhārayiṣye mumūrṣur udagāyane | yasya datto varo mahān pitrā tena mahātmanā ||
Therefore, though longing to depart, I shall sustain my life until the sun turns to its northward course (uttarāyaṇa). Let the great boon granted to me by my noble father be fulfilled—that I may meet death only when I myself choose. Until the appointed time for relinquishing life arrives, I will surely hold these vital breaths within me.
संजय उवाच
The verse highlights self-control and fidelity to a vow: even when death is desired, one may uphold dharma by sustaining life until the rightful, chosen, and cosmically appropriate time—honoring a boon and exercising disciplined agency over one’s end.
Bhīṣma, lying on the battlefield, resolves to keep himself alive until uttarāyaṇa. He intends to make true the boon from his father that he can die at will, so he restrains his prāṇas until the moment he chooses to depart.
