Bhagavad Gita · Chapter 18: Freedom through Renunciation
Bhagavad Gita 18.20
सर्वभूतेषु येनैकं भावमव्ययमीक्षते ।
अविभक्तं विभक्तेषु तज्ज्ञानं विद्धि सात्त्विकम् ॥
sarvabhūteṣu yenaikaṃ bhāvamavyayamīkṣate | avibhaktaṃ vibhakteṣu tajjñānaṃ viddhi sāttvikam ||
The knowledge by which a person sees one imperishable reality in all beings, undivided among the divided: know that knowledge to be of clarity.
Modern context
Sattvic knowledge sees one imperishable reality in all beings, undivided among the divided. It does not deny differences, but sees what unites beneath them. This is the kind of knowledge that makes a person kind, because it sees the same life in everyone. It is the opposite of the 'us and them' thinking that leads to conflict.
