Śaṅkarācārya's commentary

They who in this manner perceive the exact distinction, now pointed out, between Kṣetra and Kṣetrajña, by the eye of wisdom, by means of that knowledge of the Self which has been generated by the teachings of the śāstra and the master (ācārya), and who also perceive the non-existence of Prakṛti, Avidyā, Avyakta, the material cause of beings — they reach Brahman, the Real, the Supreme Self, and assume no more bodies.
