1 Gita Sloka  Every Day - Chapter 18 - Moksha Sanyasa Yoga - Sloka 10

Na dveshti akushalam karma kushale na anusajjate I

Tyagi sattva samavishtah medhavi chinna sanshayah II sloka 10

न द्वेष्टि अकुशलम् कर्म कुशले न अनुसज्जते I 

त्यागी सत्त्व समाविष्टः मेधावी चिन्न संशयः II श्लोक 10

The relinquisher imbued with sattva and a steady understanding and with his doubts dispelled, hates not a disagreeable work nor is he attached to an agreeable one.

A wise person; who possesses sattva quality; who knows the real truth about Brahman; who is clear of all doubts; who gives up the thought that he is the doer; who gives up the desire for fruits of karmas;

Such a person does not hate bad works, which produce undesirable results and which are done by him inadvertently by mistake. He does noot also become attached to good works, which yield desirable fruits like swarga, sons, wealth and so on.

Therefore tyaga, which is in accordance with shastras, means giving up the sense of doership, attachment and fruits in regard to karmas (as explained in sloka 4); and not giving up of karmas themselves.
