You probably know the song Imagine by John Lennon, which says, "Imagine there's no countries. It isn't hard to do.... Imagine no possessions. It's easy if you try." Well, let's look at the reality of countries and possessions here.
The song invites us to imagine there is no heaven or hell, there are no countries, no religion, and no possessions. In a way it invites us to imagine there are no limits. Really what we need to do is stop imagining that there are limits. Leaving heaven, hell and religion aside for now, certainly countries and possessions are imaginary.
Countries are set by imaginary boundaries that humans have defined. The planet is not naturally divided into countries. Humans through history have fought over land and sea boundaries, and it continues to this day. Ultimately these man-made limits end up limiting and defining us. We believe that we are Welsh, English, French, American etc. But truly we are not this.
When our claimed boundaries are threatened we strengthen them. As apparently separate individuals and separate nations, our imaginary limits harden the more they are threatened. The human ego defends itself and strengthens its boundaries, and the collective ego does the same. But these ego limits are false. There are no true limits that define us, only imaginary ones.
Equally possessions are imaginary. We have no right of ownership of anything except under human law. Possession and ownership is again man-made. If I create something, if I buy something, or if something is given to me I may think that I own it. But the planet has no system of ownership. It is a human belief of ownership, but there is no universal law of ownership which makes possession true. It is a case of man-made limitations again.
I'm not suggesting here that we give up all possessions, as we truly have none. Better to give up the belief that possession is true. Also, I do not suggest that nations let go of their borders. Better to recognise that borders are not true and let go of the false belief that we are separate and different. There is a oneness that underlies the variety of the world. It is an infinite unlimited oneness. Believing that we are limited is an error.
