Śaṅkarācārya's commentary

The union between Kṣetra and Kṣetrajña, between the object and the subject, which are opposed to each other in nature, is of the nature of mutual adhyāsa; i.e., it consists in confounding them as well as their attributes with each other owing to the absence of a discrimination between the nature of Kṣetra and that of Kṣetrajña, like the union of a rope and a mother-of-pearl respectively with a snake and silver when they are mistaken one for the other owing to the absence of discrimination. This illusion vanishes when a man attains to a knowledge of the distinction between Kṣetra and Kṣetrajña as defined in the śāstra, when he is able to separate Kṣetrajña from Kṣetra like the iṣīkā reed from the muñja-grass and to realise that Brahman, the Knowable, is his own Self. As the cause of birth has vanished in the case of such a man, it stands to reason that the wise man is not born again.
