All beliefs are wrong. Everything that you believe is wrong. That sounds a bit blunt, but there is some relative truth to it. Beliefs themselves are based on flawed logic. It's not really possible to know Truth, so to believe that some knowledge is true is flawed.

For example, one may believe that the planet is spherical. It's not true. I don't mean that the Earth is flat. I mean that the Earth isn't really truly spherical. It's not a true sphere, and not just because it bulges at the equator. The planet only appears smoothly spherical from a distance. Up close there are jagged mountains, skyscrapers, cliff edges, and so on. Also, we can't really say where planet Earth stops being the planet and starts being space. There isn't really a fixed defining perimeter where Earth's atmosphere ends. So the theory that Earth is round is flawed.

No theory is accurate. It's just that some theories are less inaccurate than others. We could say that Earth is fairly spherical, and that's less inaccurate than some other theories, but they will all be flawed to a greater or lesser degree. The simple reason for this is that Truth is inexpressible. For there to be any expression, such as a written theory, a verbal argument or a conceptual belief, it must utilise a duality. Written words are contrasted with the empty page, verbal words are contrasted with silence, and beliefs are contrasted with the empty mind in which they formulate. This duality is itself flawed. There can't really be a duality. There can only be an appearance of division or separation within the Singularity of existence. A Singularity can't really be expressed. It is best to accept that the expression of the Singularity is an inferior appearance of the reality which is always here.

What that means is that, as Reality is a Singularity, it can only be expressed as what it is not. For instance, silence can't really be expressed. Descriptions of silence aren't it. We can whisper or describe silence as the absence of sound, but that will not be as accurate as the silence itself. So all descriptions of it fail, or at best point to what can't be described. It is the same with trying to describe Reality. It's like trying to point to the finger that points, or trying to see the eye that sees.

So it's useful to recognise that all our beliefs are flawed. If we believe something to be true, it may be relatively true, but not absolute Truth. The absolute Truth is just what is, right here and now. It is beyond words and beyond concepts, or rather it is wordless and concept free, yet all words and concepts appear and disappear within it. Truth does not need to be believed. It is always here, ever-present. This is why in Non-Duality practice the aim is to drop all beliefs, even the belief of Non-Duality, as these beliefs are like clouds that block the clear sky of what just is.
