We cultivate peace. Cultivate it from within ourselves, from lives and times when our souls realized a modicum of it. And we draw that into our imagination, from darkness into light, we create it.
Corn is natural, that it will evolve depending upon how it is cultivated through any means, is also natural. We are no different, in that natural latent talents, abilities, even the ability to conceive and create peace, lies within us and can be applied without.
What you see is the aftereffect of what you were able to conceive and believe, that which your emotions have impreganted the subconscious to give birth to. You can give birth to anything, what are you planting?
I understand what you are saying. I conceive a world of peace. I conceive the possibility of humans being what some say they have never been before. The way of violence, cf competition and oppression will naturally come to an end just as a train comes to the end of the track it is on. That may be a fantasy but hey without the dreamer we would still be living in caves because if you can't dream of a house you can't build one.
My plans? I have peace in my life right now. It isn't something I have to plan for. Just avoid the things that would destroy it. Than again if peace is in my mind it cannot be destroyed. The memory of it would always be there but I can avoid visiting the place where it is.
