If I was destined to burn in separation from the cupbearer, you should have at least made me the lamp at the entrance of the tavern.

Here, the poet offers a tender and wistful lament to fate. He says that if he was destined to burn continuously in the agonizing separation from the Beloved (the Saqi), he should at least have been made the lamp at the tavern's doorstep. That way, even while burning away to ash, he could still catch glimpses of the Beloved entering and leaving, finding solace in proximity despite the torment.
