Bhagavad-gītā As It Is · Text 18.20
Knowledge, action, determination and happiness in the modes
सर्वभूतेषु येनैकं भावमव्ययमीक्षते ।
अविभक्तं विभक्तेषु तज्ज्ञानं विद्धि सात्त्विकम् ॥ २० ॥
sarva-bhūteṣu yenaikaṁ
bhāvam avyayam īkṣate
avibhaktaṁ vibhakteṣu
taj jñānaṁ viddhi sāttvikam
That knowledge by which one undivided spiritual nature is seen in all living entities, though they are divided into innumerable forms, you should understand to be in the mode of goodness.
