Srimad Bhagavatam Canto 04, Chapter 29, Text 58

SB 4.29.58

karmany arabhate yena
 puman iha vihaya tam
amutranyena dehena
 justani sa yad asnute
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The results of whatever a living entity does in this life are enjoyed in the next life.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:  
 
A person generally does not know how one body is linked with another body. How is it possible that one suffers or enjoys the results of activities in this body in yet another body in the next life? This is a question the King wants Narada Muni to answer. How may one have a human body in this life and not have a human body in the next? Even great philosophers and scientists cannot account for the transferal of karma from one body to another. As we experience, every individual soul has an individual body, and one person’s activities or one body’s activities are not enjoyed or suffered by another body or another person. The question is how the activities of one body are suffered or enjoyed in the next.
