क्षेत्रज्ञं चापि मां विद्धि सर्वक्षेत्रेषु भारत ।क्षेत्रक्षेत्रज्ञयोर्ज्ञानं यत्तज्ज्ञानं मतं मम ॥
kṣetrajñaṃ cāpi māṃ viddhi sarvakṣetreṣu bhāratakṣetrakṣetrajñayorjñānaṃ yattajjñānaṃ mataṃ mama
Understand Me as the Knower of the Field in all Fields, O Bharata; it is the knowledge at once of the Field and its Knower which is the real illumination and only wisdom.
Gītā 13·3This wider body too is only the individual field; there is a larger, a universal, a world-body, a world-field of the same Knower. For in each embodied creature there is this one Knower:
… it is when the knower of the field turns from the field itself to learn of himself within it and of all that is behind its appearances that real knowledge begins, jñānam,—the true knowledge of the field no less than of the knower.
