Srimad Bhagavatam
Canto 10 Chapter 24 Text 13

sri-bhagavan uvaca
karmana jayate jantuh
karmanaiva praliyate
sukham duhkham bhayam ksemam
karmanaivabhipadyate

TRANSLATION
Lord Krsna said: It is by the force of karma that a living entity takes birth, and it is by karma alone that he meets his destruction. His happiness, distress, fear and sense of security all arise as the effects of karma.
