Karma-Phala Rahasya and the Ethics of Dāna (कर्मफल-रहस्यं दानधर्मश्च)
जीर्यन्ति जीर्यतः केशा दन्ता जीर्यन्ति जीर्यत: । चक्षु:श्रोत्रे च जीर्येते तृष्णैका न तु जीर्यते
jīryanti jīryataḥ keśā dantā jīryanti jīryataḥ | cakṣuḥśrotre ca jīryete tṛṣṇaikā na tu jīryate ||
Bhishma berkata: “Ketika manusia menua, rambut menipis dan rontok; gigi pun lapuk dimakan usia. Mata dan telinga juga melemah. Namun hanya dahaga keinginan yang tidak menua—ia tetap selalu terasa baru.”
भीष्म उवाच
Physical faculties inevitably decline with age, but craving (tṛṣṇā) can remain undiminished; therefore one should cultivate restraint and detachment deliberately, rather than assuming old age will automatically end desire.
In Anuśāsana Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma and right conduct; here he offers a reflective maxim about aging to underscore the moral need to govern desire.
