For me one of the most exciting things about Scientology is when groups, missions and churches open up in new countries.
Dianetics: the Modern Science of Mental Health is available in over 50 languages. And because it is so simple to learn to use the techniques in these books, people frtom all over the world can read it and start to use it to help one another.
For example here are some of the languages that it is published in:
Vietnamese - Dianetics
Sinhalese - Dianetics
Arabic - Dianetics: The Modern Science of Mental Health by L. Ron Hubbard
Georgian - Dianetics: The Modern Science of Mental Health by L. Ron Hubbard
Of course Dianetics is also available in Italian and there are many Scientology Churches and missions in Italy
Here's a site that gives a lot more information on Dianetics and on the expansion of Scientology into new countries, in a question and answer form. It answers many of the questions I find people know to Scientology or Dianetics tend to ask:
