Thanks again for your beneficial answer, it was necessary this explanation to understand what you meant in your previous post and to review my beliefs.
My intention was not to enter into metaphysics. I just wanted to say that we don't create this characteristic of things. It's not that they are unsatisfactory because we want them to be so. They are unsatisfactory due to another reason. I said it was so because it is part of them to be like that (again, didn't mean metaphysics, I agree we only perceive them and can't "reach their nature" beyond our experience). You say the reason is our wish for them to be otherwise, to be different. I agree with this, I agree our wish for them to be permanent makes them unsatisfactory and not fit but this very "reaction" to our wish is not created by us. This reaction of that as soon as we expect something to be permanent it becomes unsatisfactory is not created by us. It's there, latent, independent of our wish for things to be satisfactory. We can't make things to not react in this way. It's law, it's Dhamma, the way the world is.
It's true that if we remove the wish for things to be otherwise, remove the wish for things to be satisfactory, the unsatisfactoriness dissapears but this is not here in this world. This is only having escaped it. In this world things react with unsatisfactoriness when seeking the opposite. The danger is still here, we don't make it disappear, We can only escape it and find safety.
I believe the Buddha directly knew things are anicca, dukkha and anatta so there must be something there to be seen directly...
If There Were No... (SN 35.18) wrote: “Bhikkhus, if there were no gratification in forms, beings would not become enamoured with them; but because there is gratification in forms, beings become enamoured with them. If there were no danger in forms, beings would not experience revulsion towards them; but because there is danger in forms, beings experience revulsion towards them. If there were no escape from forms, beings would not escape from them; but because there is an escape from forms, beings escape from them.
“Bhikkhus, if there were no gratification in sounds … … in odours … in tastes … in tactile objects … in mental phenomena, beings would not become enamoured with it … but because there is an escape from mental phenomena, beings escape from it.
“So long, bhikkhus, as beings have not directly known as they really are the gratification as gratification, the danger as danger, and the escape as escape in the case of these six external sense bases, they have not escaped from this world with its devas, Mara, and Brahma, from this generation with its ascetics and brahmins, its devas and humans; they have not become detached from it, released from it, nor do they dwell with a mind rid of barriers. But when beings have directly known all this as it really is, then they have escaped from this world with its devas and humans … they have become detached from it, released from it, and they dwell with a mind rid of barriers.”
