बुद्धिरध्यात्ममित्याहुर्यथावदभिदर्शिन: । बोद्धव्यमधिभूतं तु क्षेत्रज्ञक्नाधिदिवतम्,यथार्थ ज्ञानी पुरुष कहते हैं कि बुद्धि अध्यात्म है, बोद्धव्य अधिभूत है और आत्मा अधिदेवता है
buddhir adhyātmam ity āhur yathāvad abhidarśinaḥ | boddhavyam adhibhūtaṃ tu kṣetrajñam adhidaivatam ||
Yājñavalkya said: “Those seers who perceive things as they truly are declare that intellect (buddhi) belongs to the adhyātma, the inner spiritual domain. The object to be known is adhibhūta, the realm of embodied elements. And the Knower of the Field (Kṣetrajña)—the Self that witnesses within—is to be understood as adhidaivata, the presiding divine principle.”

Experience can be understood through a threefold framework: buddhi (intellect) is the inner spiritual domain (adhyātma), the knowable objects belong to the material/embodied domain (adhibhūta), and the kṣetrajña—the witnessing Self—is the presiding divine principle (adhidaivata). This encourages discernment: do not confuse external objects with the inner witness, and recognize the governing consciousness behind cognition.
In Śānti Parva’s instructional setting, the sage Yājñavalkya is expounding a philosophical classification to clarify how knowledge operates—distinguishing the inner instrument of knowing (buddhi), the external field of objects (adhibhūta), and the indwelling knower (kṣetrajña/adhidaivata).
