You take these “ownership rights” so seriously that you start wars over them and kill and die over them—when the truth is, you cannot ever “own” any part of a planet in the solar system, even if it is a planet on which your species evolved.
You are all merely stewards, seeking to take good care of that over which you have been given steward-ship—including your bodies, the bodies of your mates and children, the land on which you live, and all else that you have in your care.
These things are not your possessions, but simply articles that have been placed in your care. They are yours temporarily, only for safekeeping. You are asked by Life Itself to sustain them, to express the Life Principle of Sustainability, but not to declare that you “own” them and that they belong to you and no one else. Such a thought is not in any lasting sense functional.
Nothing that is possessed by anyone is possessed by them forever. Nothing. Things may be in your possession, but they are not your possessions.
Ownership is a temporary fiction. It is an invention of the mind and, like all mental constructions, it is temporary, having nothing to do with ultimate reality.
As with all of your social conventions, the idea of ownership arises from the fallacies that you hold as firm beliefs—in this case, the Second Fallacy About Life, which is that there is “not enough” of whatever it is you think you need to be happy.
There is enough of everything you really need to be happy, but you do not believe it, and so you seek to “own” whatever it is that you most desire, imagining that if you own it, you can keep it forever, that no one can take it away from you, that you can do what you want with it—and that from this experience of ownership will come your security, your sustainability, and your happiness.
Nothing could be further from the truth, as anyone who “owns” many things can tell you. Still, the idea persists.
This idea that you can own things has caused more harm to your psyche and more damage to your species than you could ever know.
This is because you think that “ownership” gives you “rights” that you do not intrinsically have.
