Brahmopadeśa: Adhipatitva-kathana, Dharma-lakṣaṇa, and Kṣetra–Kṣetrajña Viveka
Book 14, Chapter 43
पुरुषस्तद् विजानीते तस्मात् क्षेत्रज्ञ उच्यते । गुणवृत्तं तथा वृत्तं क्षेत्रज्ञ: परिपश्यति
puruṣas tad vijānīte tasmāt kṣetrajña ucyate | guṇa-vṛttaṃ tathā vṛttaṃ kṣetrajñaḥ paripaśyati |
Wika ni Vāyu: “Ang panloob na Persona (puruṣa) ang nakaaalam ng larangang iyon; kaya siya tinatawag na Nakaaalam ng Larangan (kṣetrajña). Malinaw na namamasdan ng Nakaaalam ng Larangan ang pag-inog ng mga guṇa at ang kanilang mga kilos. Ngunit ang mga guṇa—bagaman paulit-ulit na sumisibol sa daigdig ng pagbabago—ay hindi tunay na nakakakilala sa Sarili.”
वायुदेव उवाच
Consciousness (the Puruṣa/Ātman) is the ‘Knower of the Field’ because it illumines and understands the changing operations of prakṛti (the guṇas). The guṇas can be observed and analyzed by the Self, but they cannot, by themselves, grasp the Self—highlighting the Self’s distinctness and transcendence over material nature.
Vāyu is instructing the listener in a philosophical discourse: he defines why the Self is termed kṣetrajña and contrasts the knowing principle (Ātman/Puruṣa) with the known, changing processes (guṇas and their activities), emphasizing discernment and inner detachment.
