7.13.28

इत्येतदात्मन: स्वार्थं सन्तं विस्मृत्य वै पुमान् । विचित्रामसति द्वैते घोरामाप्नोति संसृतिम् ॥ २८ ॥

ity etad atmanah svartham santam vismrtya vai puman vicitram asati dvaite ghoram apnoti samsrtim

iti
in this way
etat
a person materially conditioned
atmanah
of his self
sva-artham
own interest
santam
existing within oneself
vismrtya
forgetting
vai
indeed
puman
the living entity
vicitram
attractive false varieties
asati
in the material world
dvaite
other than the self
ghoram
very fearful (due to continuous acceptance of birth and death)
apnoti
one becomes entangled
samsrtim
in material existence

In this way the conditioned soul living within the body forgets his self-interest because he identifies himself with the body. Because the body is material, his natural tendency is to be attracted by the varieties of the material world. Thus the living entity suffers the miseries of material existence.
