The Church of Scientology volunteers 50 millions hours of global humanitarian aid, education & disaster relief through volunteer organizations.
Why?
Help is a basic concept in the Scientology religion.
Here is one of the points L. Ron Hubbard makes on the subject:
“The greatest ability in the whole human race and all amongst the livingness, is the ability to help. And when you can improve that ability all the way up along the line, you’ve improved about all there is to improve about a person.”
— L. Ron Hubbard
