You look at possible life events in a brochure which precicely and specifically tells you exactly what will happen and what the results of this will be.
You find one you don't like the look of, some tragedy or a sickness or a guilt trip, and you almost want to skip past it. But then you take a look at the list of benefits that arise from the experience.
These include an increased ability to love yourself, an enhanced sense of compassion for others, a greater awareness of who you really are, the opportunity to help others to learn how to care more, and perhaps an increased sense of joy once you finally learn to let go of the experience.
You weigh up your options. You say, well, the experience sounds like it SUCKS, but the payoff is huge. So then you say, well, what's there to lose, since I'm immortal spirit and can't really be hurt.
From that vantage point, you decide that the benefits are worth the hassle, so you say yep, sign me up. I'll go on that trip.
Then you incarnate, and so it unfolds. And you forget you chose it. And then it happens and you think it sucks, which it does. But then you start to learn the benefits of the experience and move past it, and you gain great spiritual rewards from it.
Later, looking back, you acknowledge yes, I got exactly what I wanted, I came away with a gift and I am much richer for it. I'm more aware now and I am closer to God. I am grateful.
Then you pick up the brochure again and go on another trip, and another, and another, until you pretty much run out of benefits that you can gain from it. You pick your last trip, knowing that it's the final one and that you just need to clean up some loose ends.
Off you go. It all happens. You wake up and receive the gift of reunion with God. And it's all been worth it.
