Srimad Bhagavatam 6.16.6

6.16.6

यथा वस्तूनि पण्यानि हेमादीनि ततस्तत: । पर्यटन्ति नरेष्वेवं जीवो योनिषु कर्तृषु ॥ ६ ॥

yatha vastuni panyani hemadini tatas tatah paryatanti naresv evam jivo yonisu kartrsu

yatha
just as
vastuni
commodities
panyani
meant for trading
hema-adini
such as gold
tatah tatah
from here to there
paryatanti
move about
naresu
among men
evam
in this way
jivah
the living entity
yonisu
in different species of life
kartrsu
in different material fathers.

Just as gold and other commodities are continually transferred from one place to another in due course of purchase and sale, so the living entity, as a result of his fruitive activities, wanders throughout the entire universe, being injected into various bodies in different species of life by one kind of father after another.
