Śaṅkarācārya's commentary

Do thou also know the Kṣetrajña, described above, to be Myself, to be the Supreme Lord, not a being of the world (saṃsāra). The Kṣetrajña who is in all Kṣetras, and who is differentiated by the manifold upādhis or Kṣetras, from Brahmā down to a clump of grass, is, you should understand, really devoid of all the various upādhis and is inaccessible to any such word or thought as 'sat' or 'asat,' existent or non-existent. As nothing else remains to be known apart from the true nature of Kṣetra, Kṣetrajña and the Īśvara, that knowledge by which the two objects of knowledge, Kṣetra and Kṣetrajña, are known is considered by Me — the Lord, Viṣṇu — to be the right knowledge.
