2.9.35

यथा महान्ति भूतानि भूतेषूच्चावचेष्वनु । प्रविष्टान्यप्रविष्टानि तथा तेषु न तेष्वहम् ॥ ३५ ॥

yatha mahanti bhutani bhutesuccavacesv anu pravistany apravistani tatha tesu na tesv aham

yatha
just as
mahanti
the universal
bhutani
elements
bhutesu ucca-avacesu
in the minute and gigantic
anu
after
pravistani
entered
apravistani
not entered
tatha
so
tesu
in them
na
not
tesu
in them
aham
Myself.

O Brahma, please know that the universal elements enter into the cosmos and at the same time do not enter into the cosmos; similarly, I Myself also exist within everything created, and at the same time I am outside of everything.
