English Translation of Sanskrit Commentary By Sri Shankaracharya's
18.10 Na devesti, he does not hate; akusalam, unbefitting; karma, action, rites and duties meant for desired results-with the idea, What is the usefulness of this which is a cause of transmigration through fresh embodiment? Na anusajjate, he does not become attached to; kusale, befitting activity, daily obligatory duties, by thinking that this is the cause of Liberation by virtue of its being the cause of purification of the mind, rise of Knowledge and steadfastness in it. That is to say, he does not entertain any liking even for it, because he finds no purpose in it.
Who, again, is he? Tyagi, the man of renunciation, who has become so by having given up attachment and rewards of action in the manner stated above. He is a tyagi who performs nityakarmas by relinishing attachment to those acts and (their) results.
Again, it is being stated as to when that person does not hate an unbefitting act and does not become attached to a befitting activity: When he has become sattva-samavistah, imbued with sattva, i.e., when he is filled with, possessed of, sattva, which is the means to the knowledge that discriminates between the Self and the not-Self; and hence medhavi, wise-endowed with intelligence (medha), intuitive experience, characterized as knowledge of the Self; one possessed of that is medhavai (wise)-; and owing to the very fact of being wise, chinnasamsayah, freed from doubts-one whose doubts created by ignorance have been sundered, one who is freed from doubts by his firm conviction that nothing but abiding in the ture nature of the Self is the supreme means to the highest Good.
The person competent (for rites and duties) who, having gradually become purified in mind through the practice of Karma-yoga in the way described above, has realized as his own Self the actionless Self, which is devoid of modifications like birth etc., he, ৷৷.having given up all actions mentally, remaining at without doing or causing (others) to do anything at all (cf. 5.13), attains steadfastness in Knowledge, which is characterized as actionless-ness. In this way, the purpose of the aforesaid Karma-yoga has been stated through the present verse.
On the other hand, since, for the unenlightened person-who, while being alified (for rites and duties), holds on to the body owing to the erroneous conception that the body is the Self, and who has the firm conviction, I am the agent, because of the persistence of his idea that the Self is the agent-it is not possible to renounce actions totally, therefore he has competence only for performing enjoined duties by giving up fruits of actions. But he is not to renounce them (actions). In order to point out this idea the Lord says:

18.10 See Comment under 18.11


English Translation of Ramanuja's Sanskrit Commentary
18.10 Thus, filled with Sattva, endowed with right knowledge, i.e., with the knowledge of the reality as it is, and as a conseence of it having all doubts shattered - he alone becomes a renouncer of attachment to work and the fruits of work. He neither hates works productive of harmful effects, nor loves others productive of worldly prosperity. Disagreeable acts are fraught with undesirable fruits; and agreeable acts bring about desirable results such as heaven, sons, cows, food etc. On account of his renouncing all results other than the Brahman and on account of his renouncing the sense of agency, he shows neither love nor hatred for above-mentioned types of works. Here sinful acts having undesirable fruits are only such acts as are inadvertently performed. For it has been taught in the Srutis that nor turning away from bad conduct is antagonistic to the production of knowledge. But one who has not ceased from bad conduct, who is not tranil, is not composed, is not of peaceful mind, cannot obtain Him by knowledge (Ka. U., 1.2.24). Thus, the abandonment according to the Sastras is renunciation of the sense of agency, attachment and fruits of actions, and not total relinishment of actions as such.

He explains this further:
