Srimad Bhagavatam 11.10.8

11.10.8

विलक्षण: स्थूलसूक्ष्माद् देहादात्मेक्षिता स्वद‍ृक् । यथाग्निर्दारुणो दाह्याद् दाहकोऽन्य: प्रकाशक: ॥ ८ ॥

vilakṣaṇaḥ sthūla-sūkṣmād dehād ātmekṣitā sva-dṛk yathāgnir dāruṇo dāhyād dāhako ’nyaḥ prakāśakaḥ

vilakṣaṇaḥ
having different characteristics
sthūla
from the gross
sūkṣmāt
and the subtle
dehāt
from the body
ātmā
the spirit soul
īkṣitā
the seer
sva-dṛk
self-enlightened
yathā
just as
agniḥ
fire
dāruṇaḥ
from firewood
dāhyāt
from that which is to be burned
dāhakaḥ
that which burns
anyaḥ
other
prakāśakaḥ
that which illuminates

Just as fire, which burns and illuminates, is different from firewood, which is to be burned to give illumination, similarly the seer within the body, the self-enlightened spirit soul, is different from the material body, which is to be illuminated by consciousness. Thus the spirit soul and the body possess different characteristics and are separate entities.
