Joined with the understanding of evenness, the wise, having become knowers, casting off the fruit born of action, the gaining of a desired or undesired body, are freed from the bondage of birth, freed while still living from the bondage that is birth itself, and go to the abode, the supreme step of Viṣṇu, named liberation, free of all ill. Or else, from 'seek refuge in the understanding' (Gītā 2.49) onward, the understanding shown is the one marked by the vision of the supreme reality, standing like the flood of water spreading on every side, born of the purity of being produced by the yoga of action, since it is heard to be directly the cause of the casting-off of merit and demerit. When is the understanding born of the purity of being produced by the practice of yoga attained? He says.

This is a brief sub-gloss. For a fuller reading of this verse, see Madhusūdana, Śaṅkara, or Rāmānuja above.

The wise, joined with the discipline of understanding, performing action while giving up the fruit born of action, are by that very means freed from the bondage of birth and go to the state free of disease. For this is well known in all the Upanishads.

Krishna states the means with 'born of action'. Giving up the fruit born of action, offering it without desire to the Lord, joined with the buddhi, becoming men of right knowledge, they reach the supreme station. That yoga is action as the means to knowledge, and knowledge is the means to release; this is the import.
