Bhagavad Gita 18.21

पृथक्त्वेन तु यज्ज्ञानं नानाभावान्पृथग्विधान्।वेत्ति सर्वेषु भूतेषु तज्ज्ञानं विद्धि राजसम्॥

pṛthaktvena tu yajjñānaṃ nānābhāvānpṛthagvidhān |vetti sarveṣu bhūteṣu tajjñānaṃ viddhi rājasam ||

But that knowledge which sees in all beings various entities of distinct kinds as being distinct from one another, know thou that knowledge to be Rajasic.

The knowledge that perceives the manifold existence in all beings as separate comes from passion.

Our plain-language meaning of this verse is waiting for scholar review.
