It is impossible to see otherwise, to see anything other than what the world is, the way the world really is. It is always one and the same world that we see, but often from shifting viewpoints of space, time and of a state of mind. This is where the viewer and the viewed, the observer and the observed, is but one. The imaginative and reflecting mind, the sensing brain, the psychological and the physical, both are just as much part of what we call a world as anything. Then, how could the mind come up with something of its own, how could the brain sense something if it was not there.
It seems our imagination interferes with our seeing, but shaping reshapes and contorting the realistic impression of the world that we get through our senses. But to imagine is just as natural as it is to think or feel. What we can imagine might not look very real, it might be surreal, but imagination itself is all real. A pink elephant with mile-long legs might not be found thumping around on the plains of Africa, but one can be in imagination, and just as it could be imagined it could be traced on paper. And therefore, real, and just as much part of the world as an elephant made of flesh and bones.
There is a world for us all to see and know that the world exists. We all see that world from our slightly different vantage points, as of our individual persons, and this is the proof that we all exist in our individual capacities. Imagine what would happen if all people would see the world in the same way: no difference of opinion, to debate, no agreements of disagreements no conversation or the use of language, and ultimately no individual mind, just one frame showing a still scene.
This is real that we all exist individually. This is real that we exist as different parts of one world. This, therefore, is also real that we see that same one world differently. I can be at one place in the city and my friend can be at another. We both are in the same city, but since we are not exactly at the same place, we are bound to have different views of the same city.
The uncertainty looms in those minds that develop an error of perception when they start believing themselves to be a thing aside from the world, that they are an observer looking at something outside – the only thing that is in the mind and is not real is absolute objectivity.
