Bhagavad Gita Chapter 17, Verse 11

अफलाकाङ्क्षिभिर्यज्ञो विधिदृष्टो य इज्यते | यष्टव्यमेवेति मनः समाधाय स सात्त्विकः ||

aphalākāṅkṣibhir yajño vidhi-dṛṣṭo ya ijyate yaṣṭavyam eveti manaḥ samādhāya sa sāttvikaḥ

The sacrifice that is performed by those who do not desire results, according to scriptural injunctions, with the mind fixed on the thought 'it should be performed'—that is sattvic.

Krishna describes sattvic sacrifice (yajña)—sacrifice that is sattvic. 'Aphalākāṅkṣibhir yajño vidhi-dṛṣṭo ya ijyate'—this sacrifice is performed (ijyate) by those who do not desire results (aphalākāṅkṣibhiḥ) and according to scriptural injunctions (vidhi-dṛṣṭaḥ). 'Yaṣṭavyam eveti manaḥ samādhāya'—with the mind (manaḥ) fixed (samādhāya) on the thought 'it should be performed' (yaṣṭavyam eva iti). 'Sa sāttvikaḥ'—that is sattvic. Sattvic sacrifice is performed without desire for results, following scriptural guidance, with the mind focused on the duty itself. It's not about getting something—it's about performing the action for its own sake, as a duty. Understanding this helps you recognize sattvic sacrifice and practice it.
