Bhagavad Gita Chapter 17, Verse 12

अभिसन्धाय तु फलं दम्भार्थमपि चैव यत् | इज्यते भरतश्रेष्ठ तं यज्ञं विद्धि राजसम् ||

abhisandhāya tu phalaṁ dambhārtham api caiva yat ijyate bharata-śreṣṭha taṁ yajñaṁ viddhi rājasam

O best of Bharata, know that sacrifice which is performed with the intention of gaining results and for the sake of show—that is rajasic.

Krishna describes rajasic sacrifice—sacrifice that is rajasic. 'Abhisandhāya tu phalaṁ dambhārtham api caiva yat ijyate'—this sacrifice is performed (ijyate) with the intention of gaining results (abhisandhāya phalam) and for the sake of show (dambhārtham). 'Taṁ yajñaṁ viddhi rājasam'—know (viddhi) that sacrifice (yajñam) to be rajasic (rājasam). Rajasic sacrifice is performed with desire for results and for show—to impress others, gain recognition, or achieve personal benefit. It's not about duty for its own sake—it's about what you'll get from it. Understanding this helps you recognize rajasic sacrifice and move toward sattvic sacrifice.
