CHĀNDOGYA UPANISHAD · 6.10.2

एवम् एव खलु सोम्येमाः सर्वाः प्रजाः सत आगम्य न विदुः सत आगच्छामह इति ।
त इह व्याघ्रो वा सिंहो वा वृको वा वराहो वा कीटो वा पतङ्गो वा दंशो वा मशको वा यद् यद् भवन्ति तद् आभवन्ति ॥

evam eva khalu somyemāḥ sarvāḥ prajāḥ sata āgamya na viduḥ sata āgacchāmaha iti ।
ta iha vyāghro vā siṃho vā vṛko vā varāho vā kīṭo vā pataṅgo vā daṃśo vā maśako vā yad yad bhavanti tad ābhavanti ॥

'In the same manner, my son, all these creatures, when they have come back from the True, know not that they have come back from the True. Whatever these creatures are here, whether a lion, or a wolf, or a boar, or a worm, or a midge, or a gnat, or a musquito, that they become again and again.
