Left with a feeling of doom

[tadeus]

The concept is that of successful graduation or failure to graduate.
So Ra and quo say: If you’ve been at least 51% of your time altruistic you go to a nice heaven and you’re gonna incarnate in a body with superhuman powers. If you’ve only been altruistic 50% of your time you need to reincarnate for other 75.000 years (probably forgetting your past at every reincarnation) in 3rd density again.

Yes - this 75.000 years or less sounds much for a life period of about 80 years.
But the concept is that time only is relevant in space/time and not in time/space.
So when you will not make a choice it should be seen as pleasure to get more time to make the choice.

The second thing is to see the "time" between the incarnations and not only the time in incarnation.
It must be seen as your life plan that you will set up for a new incarnation again and again until you will fulfill the choice.

Maybe it is helpful to read a little bit from Rudolf Steiner?
He is writing about the concepts specially here on earth and more about what is going on between the incarnations.
So Ra can help to understand the "galactical concept" of the creation with a view from an "outer" perspective.
When you want to learn more aspects about the "inner" perspective of life on earth maybe Rudolf Steiner can give you some facets for understanding this better.
