All is experience and when a final curtain falls it means that is the end of one kind of experience. But the chance for new experiences from the growth presented by having those experiences.
Life is a series of challenges. Each one can be seen to be slightly harder than the last, but only when the preceding experience has been assimilated fully and understood. Otherwise that experience is likely to repeat itself, but only until the chance for more of experience is taken away. Then its a possibility lost.
Life is said to be a learning ground, with a learning curve; a shallow one for the careful and a extremely steep one for the brave. But sadly, this cannot be proven. Especially in the light of this being but a holographic world made from thought forms with captured sparks being used like lab rats for another race to study. It might all really just be in vain.
What always lies ahead is a path of the foreseen and the unforeseen. With the travellers of the path hoping for experiences they can have foreseen with others they can manage when they arise. For some this final curtain call will have come as a shock; a difficult change to their lives. But for others it will have been foreseen, and adjustments will have been made in plenty of time. Life is like that ... being ready for the unforeseen is something that is part of the survival pack of life.
