Sempiternal
That won't change and is unaffected by time. Anytime I get lost in the wilderness I get the feeling ever stronger that we dare take this world as ours and that the nature somehow bends to our boundaries. It is like setting limits to a soul our trying to put rules on feelings. Who are we to say when it is okay or not for one to end it's life? Who can dare pretend that there are rules to affection, the gender does matter?
Just like the mountains are set afire every night by a source billions of miles away, but hnchanged, only enlighten by it, we have to learn to let our core be untammed, but shine through our learnings, scares and differences.
