Bhagavad Gita 13.2

क्षेत्रज्ञं चापि मां विद्धि सर्वक्षेत्रेषु भारत।क्षेत्रक्षेत्रज्ञयोर्ज्ञानं यत्तज्ज्ञानं मतं मम॥

kṣetrajñaṃ cāpi māṃ viddhi sarvakṣetreṣu bhārata |kṣetrakṣetrajñayorjñānaṃ yattajjñānaṃ mataṃ mama ||

Do thou also know Me as the knower of the field in all fields, O Arjuna. Knowledge of both the field and the knower of the field is considered by Me to be the knowledge.

I am the omniscient Self that abides in the realm of matter; knowledge of matter and of the all-knowing Self is wisdom.

Our plain-language meaning of this verse is waiting for scholar review.
