Canto 10 Chapter 82 Text 45

aham hi sarva-bhutanam
adir anto ’ntaram bahih
bhautikanam yatha kham var
bhur vayur jyotir anganah

TRANSLATION
Dear ladies, I am the beginning and end of all created beings and exist both within and without them, just as the elements ether, water, earth, air and fire are the beginning and end of all material objects and exist both within and without them.
