Once you accept the idea of past lives, then you accept the idea of a multitude of future lives. Once you do THAT, then this current life shrinks in importance into insignificance.Regarding "stable data" previously mentioned, probably the most significant one in scientology is past lives. Most scientologists look at, experience or imagine past lives, take your pick. Elron obsessed on the past "going back" ever further in uncountable numbers of years apparently attempting to discover the beginning of existence, assuming such a thing exists. (What existed before existence?)
That was the whole point. Once you get people to consider this current life to be unimportant, it's easier to convince them to sacrifice it to the Cause.
