Bhagavad Gita 18.10

न द्वेष्ट्यकुशलं कर्म कुशले नानुषज्जते।त्यागी सत्त्वसमाविष्टो मेधावी छिन्नसंशयः॥

na dveṣṭyakuśalaṃ karma kuśale nānuṣajjate |tyāgī sattvasamāviṣṭo medhāvī chinnasaṃśayaḥ ||

The man of renunciation, pervaded by purity, intelligent, and with his doubts cut asunder, does not hate an unpleasant task nor is he attached to a pleasant one.

The wise man who has attained purity, whose doubts are resolved, who is filled with the spirit of self-abnegation, does not shy away from action due to its pain, nor does he crave it due to its pleasure.

Our plain-language meaning of this verse is waiting for scholar review.
