But a sacrifice that is offered with an eye on its reward, or simply for show, O best of the Bharatas, know that sacrifice to be rajasic.
Explanation
Krishna is describing three kinds of sacrifice (yajña), a ritual offering made as worship or duty, matching the three qualities (guṇa) of nature. Having just described the sattvic kind, done as a duty without wanting a reward, he now says that a rite done for a reward (phala) or to show off (dambha) is rajasic, driven by passion and desire. He addresses Arjuna as 'best of the Bharatas'.
