If this is the only desire, O Shayar, then we too shall come, taking payment.

This couplet is a sharp, cynical commentary on the nature of passion and art. The speaker addresses the 'Qasid' (messenger/messenger of desire), suggesting that if the messenger's passion is genuine, then the speaker's participation will also be measured and transactional. The implication is clear: in today's world, even deep emotions and artistic pursuits have a price tag. It's a brilliant critique of commercialism!
