Why we need reviews.


In an ancient monastery in a far away place, a new monk arrived to join his brothers in copying books and scrolls in the monastery's scriptorium. He was assigned as a rubricate on copies of books that had already been copied by hand.

One day, while working on the monks' Book of Vows, he asks old Father Florian, the Armarius of the Scriptorium, 'Does not the copying by hand of other copies allow for chances of error? How do we know we are not copying the mistakes of someone else? Are they ever checked against the original?'

Fr. Florian was set back a bit by the obvious logical observation of this youthful monk. 'A very good point, my son. I will take one of the latest copies of the Book of Vows down to the vault and compare it against the original.' Fr. Florian went down to the secured vault and began his verification.

A day passed and the monks began to worry and went down looking for the old priest. They were sure something may have happened. As they approached the vault they heard sobbing and wailing... they opened the door and found Fr. Florian crying over the new copy and the original, ancient Book of Vows, both opened before him on the table. It was obvious to all that the poor man had been crying his old heart out for a long time.

'What is the problem, Reverend Father???' asked one of the monks.

'Oh, my Lord,' sobbed the priest, 'The word is 'CELEBRATE'!!!'

And this is why we need reviews.

zen and moon

A Zen Master lived the simplest kind of life in a little hut at the foot of a mountain. One evening, while he was away, a thief sneaked into the hut only to find there was nothing in it to steal. The Zen Master returned and found him. "You have come a long way to visit me," he told the prowler, "and you should not return empty handed. Please take my clothes as a gift." The thief was bewildered, but he took the clothes and ran away. The Master sat naked, watching the moon. "Poor fellow," he mused, " I wish I could give him this beautiful moon."

zen and tea cup

A university professor went to visit a famous Zen master. While the master quietly served tea, the professor talked about Zen. The master poured the visitor's cup to the brim, and then kept pouring. The professor watched the overflowing cup until he could no longer restrain himself. "It's overfull! No more will go in!" the professor blurted. "You are like this cup," the master replied, "How can I show you Zen unless you first empty your cup."
