7.2.43

यथानलो दारुषु भिन्न ईयते यथानिलो देहगत: पृथक् स्थित: । यथा नभ: सर्वगतं न सज्जते तथा पुमान् सर्वगुणाश्रय: पर: ॥ ४३ ॥

yathanalo darusu bhinna iyate yathanilo deha-gatah prthak sthitah yatha nabhah sarva-gatam na sajjate tatha puman sarva-gunasrayah parah

yatha
just as
analah
the fire
darusu
in wood
bhinnah

iyate
is perceived
yatha
just as
anilah
the air
deha-gatah
within the body
prthak

sthitah
situated
yatha
just as
nabhah
the sky
sarva-gatam
all-pervading
na
not
sajjate
mix
tatha
similarly
puman
the living entity
sarva-guna-asrayah
although now the shelter of the modes of material nature
parah
transcendental to material contamination

As fire, although situated in wood, is perceived to be different from the wood, as air, although situated within the mouth and nostrils, is perceived to be separate, and as the sky, although all-pervading, never mixes with anything, so the living entity, although now encaged within the material body, of which it is the source, is separate from it.
