That Hubbard guy is a wacko. Read some of this:

Here are some sections I cut and paste:
He says that the research began with his 1938 book, Excalibur, which appears to have been the manuscript he claims was stolen by the Russians. During these twelve years, especially in the last three or four before Dianetics came out, he wrote at least seventy-eight science fiction stories alone (under his name, or the pseudonyms of Rene Lafayette and Kurt Van Strachen){11} not to mention writing in other fields. With all this writing, it's hard to believe he had the time to research those 270 subjects properly (to research them properly would require 540 people; a control group that has not been given the Dianetic treatment should have been included in the sample).

The Australian Inquiry finally came to the conclusion that Hubbard's "sanity was to be gravely doubted."{30} Certainly some of Hubbard's statements, even coming from a former science fiction writer, do sound rather strange. Hubbard claims to have visited Venus, the Van Allen Radiation belt,{31} and heaven -- twice. The first time in heaven, he said, was from "the moment of the implant to forget ... 43,891,832,611,177 years 344 days, 10 hours, 20 minutes and 40 seconds from 10:02 to 2 P.M. Daylight Greenwich Time, May 9, 1963."{32} The second time was about a trillion years later. Lest anyone doubt he was there, or think that he might have ended up in the wrong place, he described Heaven as follows:
The gates of the first series are well done, well built. An Avenue of statues of saints leads up to them. The gate pillars are surmounted by marble angels. The entering grounds are very well kept, laid out like Bush Gardens in Pasadena, so often seen in the movies.
The second series ... is shabby. The vegetation is gone. The pillars are scruffy. The saints have vanished. So have the angels. A sign on one (the left as you enter) says "This is Heaven." The right one says "Hell."
In addition to having visited Heaven, Hubbard has also rewritten Genesis.{33} "Before the Beginning was a Cause and the entire purpose of the Cause was the creation of effect," etc. He has also rewritten the calendar{34} to read "A.D. 1, A.D. 10," etc., (to stand for "After Dianetics 1951," "After Dianetics 1960"
, as if his discoveries were as important as the birth of Christ. When Hubbard first came out with Dianetics he wrote that it was a "milestone for Man comparable to his discovery of fire and superior to his invention of the wheel and arch."{35} Now he sees Scientology as purer than Buddhism, Taoism and Christianity.{36}
