Bhagavad Gita 13.3

क्षेत्रज्ञं चापि मां विद्धि सर्वक्षेत्रेषु भारत।क्षेत्रक्षेत्रज्ञयोर्ज्ञानं यत्तज्ज्ञानं मतं मम ॥१३.३॥

kṣetrajñaṃ cāpi māṃ viddhi sarvakṣetreṣu bhāratakṣetrakṣetrajñayorjñānaṃ 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.
