L. Ron Hubbard: The Founder of Scientology continued...
By the age of nineteen, long before the advent of commercial airplane or jet transportation, he had traveled more than a quarter of a million miles, including voyages not only to China but also Japan, Guam, the Philippines and other points in the Orient. In a very real sense, the world itself was his classroom, and he studied in it voraciously, recording what he saw and learned in his ever-present diaries, which he carefully preserved for future reference.
Everywhere he went, he also took the time to help and teach others. On a remote Pacific island, for example, he proved to the terrified natives that the groans of a ghost in a supposedly haunted cave were nothing more than the rushing of underground water.
