Offering for a reward

abhisandhāya tu phalaṃ dambhārthamapi caiva yatijyate bharataśreṣṭha taṃ yajñaṃ viddhi rājasam

But an offering made with an eye on the reward, or just for show, best of the Bharatas, know it is restless.

What it means

Krishna describes rajasic yajna, a restless offering. It's done for a reward, or to be seen. Not wrong exactly, but transactional. Like giving a present mainly so they'll owe you one. The motive turns a sacred act into a deal.

The story

Arjuna has watched kings perform huge ceremonies to win favour and fame. Krishna names the motive behind the gold.

In your life

Maybe you know someone who volunteers mainly for their CV, and drops it the moment they get the job. Next time you help, notice whether you're keeping score.
