Is there a need for death in fourth density?

[Anders]

So one guess I have is that 90,000 years means the approximate time for fourth density to reach fifth density, without the need for any physical death of the body.

Ra spoke of the duration of a fourth density cycle that is around millions of years and in the material it's quite clear that the only short density is the third.

I found this:

"Questioner: How long is a cycle of experience in fourth density in our years?

Ra: The cycle of experience is approximately 30 million of your years if the entities are not capable of being harvested sooner. There is in this density a harvest which is completely the function of the readiness of the social memory complex. It is not structured as is your own, for it deals with a more transparent distortion of the One Infinite Creator." - Law of One 43.13

I'm just guessing here, but I still suspect that Ra used the Law of Confusion to avoid stating measurements of time directly. If the structure of the SMC is more transparent then it will be harvested as soon as it can, meaning much sooner than 30 million years. 90,000 years in fourth density seems more reasonable to me than 30 million years.
