Two rabbinical students were caught by the Rabbi gambling and drinking in
the company of undesirable characters -- even before the sun set on the
evening of the Sabbath. The Rabbi called them into his study the next day.
Both confessed to having given in to weakness, and admitted that they
deserved punishment. The Rabbi thought and then went into his kitchen and
brought back two bags of dried peas. "Put these in your shoes," he told
them, "and walk on them for a week, to remiond yourself how hard life can
be when you turn away from the Law."
A few days later the two students met. One was limping terribly, had dark
circles under his eyes, and looked very tired. The other seemed much as he
had been the week before.
"Hey," said the first. "How is it that you are walking so freely. Didn't
you do as the Rabbi told us and put the peas in your shoes."
"Of course I did," said the other. "How could I disobey the Rabbi?" He
started to walk away, paused and then said "But I boiled them first."
