Here is the specific story I told to Paulo Coelho about the stone at St Joseph's party:
I was asked by Paulo to attend St Joseph's party on early November.
But I did not answer immediately, I wrote to Paulo let me think for a while.
I was not sure if I could save a money to go to Istanbul.
Of course, I did want to attend the party and meet with Paulo but I left this for a while to think.
On one late November, my wife Yumi went to her friend's exhibition at Tokyo.
This Yumi's friend, is a handicraft artist making necklaces with stones.
She invited us to her exhibition, but I was away to do my job so Yumi went ahead to the exhibition, I decided to go to the exhibition after I finish my job.
When Yumi entered the gallery, she saw more than a hundred beautiful necklaces hanged on the walls.
All of those necklaces were using what they call power stone as a motif.
After having a little conversation, the artist asked Yumi which necklace she likes the best.
There were several kinds of necklaces hanged on the wall, all of them were using different kinds of stones.
Yumi immediately pointed the necklace using a blue stone.
"That's interesting that you've chosen that stone"
The artist said to Yumi.
After an hour or so,
after I finished a job, I arrived the gallery.
Yumi asked me a same question that she was asked.
"Which necklace do you like the best?"
After looking at them for a while, I pointed the same necklace out of a hundred necklaces.
It was the same necklace that Yumi have chosen.
"The name of the stone on this necklace is Aqua Aura"
the artist started describing to us.
"Aqua Aura is very good for a creative people. The stone makes the people connect to universe. And it is related to throat chakra, so this stone is also very good for the people who sings (note: Yumi is a very good singer)"
To be very honest, I was reading many spiritual books, but I did not believe in stone power, but Yumi believed in it.
The artist continued:
"the stone is a natural crystal but it wasn't originally blue when it was mined from the ground.
It is turned blue by an alchemical process using gold.
So this Aqua Aura is also called Alchemist Stone"
Yumi screamed when she heard this (I didn't scream, but I was very surprised).
We were talking what to do about St Joseph's party for many days.
Yumi started explaining to the artist why she screamed.
After hearing Yumi's story, the artist told us that she is also a Paulo Coelho's fan.
So this was the the day we've decided to go Istanbul.
I felt like I have to give this stone to Paulo.
