रामायण - अयोध्या - आयुष्य

अहोरात्राणि गच्छन्ति सर्वेषां प्राणिनामिह ।
आयूंषि क्षपयन्त्याशु ग्रीष्मे जलमिवांशवः ॥

- रामायण, अयोध्या

ahorAtrANi gacChanti sarveShAm prANinAm iha ।
AyUmShi kShapayanti Ashu grIShme jalam iva AmshavaH ॥

- rAmAyaNa, ayodhyA

Every being goes through the experience of day and night every day. Just like the sun rays sucks in water during the Greeshma month, the cycle of day and night erode our longevity.

- Ramayana, Ayodhya
