(Like the old bards - your illustrious predecessors -) you should plead before that symbol of generosity that the ministrel was a cripple, that the distance to be covered was long and tedious and as such the alms may kindly be bestowed on him here.
Note: With چوٽاڻي signifying Allah, the verse may mean that the seeker was crippled by his sins.and the Divine commandments were of a sizeable number. These facts had made his spiritual evolution well nigh impossible. He should therefore repent of his sins and seek forgiveness of Allah which may be granted before he dies and crosses the border. But if چوٽاڻي is interpreted as the Prophet, then the verse would mean that due to age, infirmity and distance the supplicant would not reach him to seek his aIms personally.

"Minstrel is weak road is long tell the generous Lord,
He cannot there, bestow something here on this bard."

Minstrel is not distance is long, convey to the elevated one,
"whatever your intend to give me, send it here, I will not come.
