Is that part of your celebration every year?
No. [laughs] There’s no religious holiday of LRH’s birthday.

That was something I actually found on Scientology.org, that there were a handful of religious holidays including his birthday.
Yeah, the special occasions which are anniversaries of things, but then they’ll basically like, on LRH’s brithday, there’ll be an event where they talk about the things that’ve happened in the past year. On the anniversary of Dianetics, they’ll talk about, you know, what countries are now having places that deliver Dianetics. So there’s stuff like that, where it’s just sort of like updates on what’s happening in the world, but nothing really more than that.
