Srimad Bhagavatam Canto 11, Chapter 20, Text 14

SB 11.20.14

etad vidvan pura mrtyor
 abhavaya ghateta sah
apramatta idam jñatva
 martyam apy artha-siddhi-dam
 
Translation: 
 
A wise person, knowing that although the material body is subject to death it can still award the perfection of one’s life, should not foolishly neglect to take advantage of this opportunity before death arrives.
