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 ||
ଭୀଷ୍ମ କହିଲେ— ମନୁଷ୍ୟ ଜୀର୍ଣ୍ଣ ହେଲେ କେଶ ଜୀର୍ଣ୍ଣ ହୋଇ ଝଡ଼ିଯାଏ; ଦାନ୍ତ ମଧ୍ୟ ଜୀର୍ଣ୍ଣ ହୋଇ ଭାଙ୍ଗିଯାଏ। ଚକ୍ଷୁ ଓ ଶ୍ରୋତ୍ର ମଧ୍ୟ କ୍ଷୀଣ ହୁଏ; କିନ୍ତୁ ତୃଷ୍ଣା ଏକା ଜୀର୍ଣ୍ଣ ହୁଏ ନାହିଁ— ସେ ସଦା ନବୀନ ରହେ।
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.
