Bhagavad Gita · Chapter 18: Freedom through Renunciation
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 the knowledge that sees in all beings many separate entities of different kinds: know that knowledge to be of passion.
Modern context
Rajasic knowledge sees only separation: many different beings, each on their own. It is not wrong exactly; things are different. But it stops at the surface. Much of competitive modern life runs on this kind of knowledge: everyone separate, everyone a rival. It is useful for some purposes but does not lead to peace.
