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 ||
ພີດສະມະ ກ່າວວ່າ: «ເມື່ອຄົນແກ່ເຖົ້າ ຜົມກໍແກ່ແລະຫຼົ່ນ; ແຂ້ວກໍເສື່ອມຕາມວັຍ. ຕາແລະຫູກໍອ່ອນແຮງລົງ. ແຕ່ຄວາມຢາກ (ຕັນຫາ) ພຽງຢ່າງດຽວບໍ່ແກ່—ມັນຍັງສົດໃໝ່ຢູ່ເສມອ».
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.
