लब्ध्वा सुदुर्लभमिदं बहुसम्भवान्ते
मानुष्यमर्थदमनित्यमपीह धीर: ।
तूर्णं यतेत न पतेदनुमृत्यु यावद्
नि:श्रेयसाय विषय: खलु सर्वत: स्यात् ॥

labdhvā sudurlabham idaṁ bahu-sambhavānte
mānuṣyam-arthadam-anityam-apīha dhīraḥ
tūrṇaṁ yateta na pated-anumṛtyu yāvad
niḥśreyasāya viṣayaḥ khalu sarvataḥ syāt

After many births, getting this rare human form which, although transient, is conducive to attain the Ultimate, a wise person should not lose time to strive for the supreme felicity before the body falls. (For,) the body is constantly followed by death, and the sense enjoyments indeed are available all around (to distract man from his ultimate objective).
