Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Moksha-Sanyasa Yoga Chapter 18, Verse 18.20.
Sanskrit
सर्वभूतेषु येनैकं भावमव्ययमीक्षते । अविभक्तं विभक्तेषु तज्ज्ञानं विद्धि सात्त्विकम् ॥ १८.२० ॥
Hindi
जिस ज्ञान से मनुष्य पृथक्-पृथक् सब भूतों में एक अविनाशी परमात्मा को विभागरहित स्वभाव से स्थित देखता है, उस ज्ञान को तो तू सात्विक जान ।
English
When one can see Eternity, Infinity, and an undivided spiritual nature in things that are mortal, perishable, and divided in their spiritual nature, he has acquired the pure SAATVIC knowledge (or the knowledge of ‘goodness,’ concerning the spiritual soul beyond the body).
