शुकस्य योगसिद्धिः (Śuka’s Yogic Attainment and Ascent)
न हाहानि निवर्तन्ते न मासा न पुन: क्षपा: | सो<थयं प्रपद्यते5ध्वानं चिराय ध्रुवमध्रुव:
na hāhāni nivartante na māsā na punaḥ kṣapāḥ | so 'thayaṃ prapadyate 'dhvānaṃ cirāya dhruvam adhruvaḥ ||
ビーシュマは言った。「日々は戻らず、月も戻らず、夜もまた戻らない。かくしてこの身を受けた者—自ら無常にして滅びゆく者—は、定まり確かなもの（死）へと向かう長い旅路に出るのである。」

Educational Q&A
Time is irreversible: days, months, and nights never return. Therefore one should live with ethical urgency and detachment, recognizing that the perishable person inevitably proceeds toward the certain end (death).
In Śānti Parva, Bhīṣma instructs on dharma and right conduct after the war. Here he emphasizes the relentless forward movement of time to ground his counsel in sobriety, restraint, and moral seriousness.
