Bhagavad Gita 18.23
नियतं सङ्गरहितमरागद्वेषतः कृतम्।अफलप्रेप्सुना कर्म यत्तत्सात्त्विकमुच्यते॥
niyataṃ saṅgarahitamarāgadveṣataḥ kṛtam |aphalaprepsunā karma yattatsāttvikamucyate ||
An action that is ordained, free from attachment, done without love or hatred, and without desire for reward is declared to be Sattvic.
An obligatory action done by one who is disinterested, who neither likes nor dislikes it, and gives no thought to the consequences that may follow, such an action is Pure.
Our plain-language meaning of this verse is waiting for scholar review.
