The five book trilogy

[manored]

As far as spiritual teachers go, Douglas Adams is a good one to choose, no?

YA :) I prefer Douglas Adams to church :)

To be fair, douglas adams doesn't put on a one hour service on a weekly basis with a handful of volunteers, most of which aren't all that bright.

I have an all in one book of the first four. Never even heard of a fifth one until now. It also has the part about How to Leave the Planet, mentioned here before. Funny stuff :D
