4.29.59

इति वेदविदां वाद: श्रूयते तत्र तत्र ह । कर्म यत्क्रियते प्रोक्तं परोक्षं न प्रकाशते ॥ ५९ ॥

iti veda-vidam vadah sruyate tatra tatra ha karma yat kriyate proktam paroksam na prakasate

iti
thus
veda-vidam
of persons who know the Vedic conclusions
vadah
the thesis
sruyate
is heard
tatra tatra
here and there
ha
certainly
karma
the activity
yat
what
kriyate
is performed
proktam
as it was said
paroksam
unknown
na prakasate
is not directly manifested.

The expert knowers of the Vedic conclusions say that one enjoys or suffers the results of his past activities. But practically it is seen that the body that performed the work in the last birth is already lost. So how is it possible to enjoy or suffer the reactions of that work in a different body?
