This one is long but is also an interesting piece of advice:

I had gone a-begging from door to door in the village path, when thy golden chariot appeared in the distance like a gorgeous dream and I wondered who was this King of all kings! My hopes rose high and methought my evil days were at an end, and I stood waiting for alms to be given unasked and for wealth scattered on all sides in the dust. The chariot stopped where I stood. Thy glance fell on me and thou camest down with a smile. I felt that the luck of my life had come at last. Then of a sudden thou didst hold out thy right hand and say `What hast thou to give to me?'

Ah, what a kingly jest was it to open thy palm to a beggar to beg! I was confused and stood undecided, and then from my wallet I slowly took out the least little grain of corn and gave it to thee. But how great my surprise when at the day's end I emptied my bag on the floor to find a least little gram of gold among the poor heap. I bitterly wept and wished that I had had the heart to give thee my all.
