Brahmopadeśa: Adhipatitva-kathana, Dharma-lakṣaṇa, and Kṣetra–Kṣetrajña Viveka
Book 14, Chapter 43
एते द्रुमाणां राजानो लोके5स्मिन् नात्र संशय: । बरगद
ete drumāṇāṁ rājāno loke 'smin nātra saṁśayaḥ | aliṅdagrahaṇo nityaḥ kṣetrajño nirguṇātmakaḥ | tasmād aliṅgaḥ kṣetrajñaḥ kevalaṁ jñānalakṣaṇaḥ ||
风神伐由说道：“这些乃此世树木之王，毫无疑问。永恒的‘知田者’（kṣetrajña，真我）不以任何外在标记而被把握，因为祂超越诸质（guṇa）。因此，知田者无可区别之相；唯有纯粹的觉知，才被承认为祂的界定特征。”

Educational Q&A
The Self (kṣetrajña) is eternal and nirguṇa—beyond material qualities—so it cannot be identified by external signs; its only true ‘mark’ is pure consciousness/knowledge (jñāna).
Vāyu-deva is instructing the listener by first asserting a worldly classification (the ‘kings’ among trees) and then pivoting to a higher teaching: the indwelling Self is not an object of sensory identification and is known only as consciousness itself.
