A baker wanted to get to know a great guru in his town a little better, so he invited him to dinner.
The day before, the guru went to the bakery disguised as a beggar, picked a bread roll off the display and began to eat it.
The baker saw this and tossed him out into the street.
The following day, the guru and a disciple went to the baker's house and were treated to a splendid banquet.
In the middle of the meal, the disciple asked, How does one tell a good man from a bad man?
Just look at this baker
He is capable of spending ten gold pieces on a banquet because I am famous, but is incapable of giving a piece of bread to feed a hungry beggar.
