If I understand you correctly [color="#ff0000"]Mur[/color] we, humans, are individual systems that have "inner suns"...
In my opinion that's correct in a way that we humans always have a void in us. We humans will never be satisfied, maybe for a time but not "infinitely" or forever.
So like your example says pain, suffering, etc. is a way to amplify our creativity and this is true. I say this is true because when ever I feel alone, sad, etc. I write poems to ease the pain and that turns into a lovely poem even if it's "made" from pain.
But what I do not know is if the point of void is either good or bad?
I'll elaborate more when you answered my question [color="#ff0000"]Mur.[/color]
