Bhagavad Gita 13.28

He who can see the Supreme Lord in all beings, the Imperishable amidst the perishable, he is the one who truly sees.

समं सर्वेषु भूतेषु तिष्ठन्तं परमेश्वरम्।विनश्यत्स्वविनश्यन्तं यः पश्यति स पश्यति॥

samaṃ sarveṣu bhūteṣu tiṣṭhantaṃ parameśvaram|vinaśyatsvavinaśyantaṃ yaḥ paśyati sa paśyati||
