People might ask, "Are you a glass half full person, or half empty?" This, of course, refers to whether you have a negative or positive outlook on life. When a glass is half filled with a drink, do you focus on there being an amount of drink there, or do focus on there being an amount missing? Really, the glass is neither half full nor half empty.

Why so? To see the glass as half full or empty is to mistake air for nothingness. It belies a way of looking at the world that is dualistic or divided. Truly the glass is always full, even when it's empty. Well, it's never empty. It only appears empty because air is invisible. But invisible isn't nothing. Air isn't nothing. Whether the glass has liquid and gas in it, or only liquid, or only gas, doesn't really matter. It's always full of something.

So that can be a game changer. It can change the way we view the world. Suddenly we see the unseen. The focus isn't on this and not that. The focus takes in the whole picture. In effect, we can move from being negative or positive to just viewing it as it is. We change from dualistic thinking to non-dualistic or holistic awareness.

Let's take a more useful example than glass with liquid and gas in it. How about when plans for meeting up with someone get cancelled? Some may see this as negative, in that something that was supposed to happen doesn't happen. Some may see it as positive, in that it frees them up for something else to happen. The Non-Dualistic way is that it is neither negative nor positive. It just is what it is. It's not that something doesn't happen. Something is always happening in the world, even when it seems that there's nothing going on. The planet continues to spin its swirling path through space. But we don't really notice that.

If we go back to the glass being full, half full or empty, there is a further step of recognition. It's what we might consider as the Zen way of looking at it. There is no glass.

How so? Can it be true that there is no glass? Yes. Truly 'the glass' cannot be defined. The glass is something like a solid form that can hold liquids and gases. But it's all vibrating energy, just at different densities. The glass may seem to be more solid that air, but it's not completely solid. Its apparent solidity is temporary and dependent on environmental conditions. At certain temperatures its solidity will turn to liquid and then to gas. And we know that although objects may seem fixed and permanent, this is only a relative appearance of permanence. All form in the universe is changing. It's just that some forms change more slowly than others. Although, to be more accurate there aren't really many forms. There isn't really a glass and water and air. It is all a flow of vibrating energy that the mind gives temporary labels to.

So there is no glass, only the temporary appearance of a substance standing out from the rest of the substance. That substance we can call Consciousness. It is Consciousness in which the apparent solids, liquids and gases are known. The glass that we know is only ever known in Consciousness, made of Consciousness, known by Consciousness.

It is all Consciousness. Consciousness is always full. Full of Everything, whilst its sum total is Nothing. Full and empty don't really apply to the Singularity of it. It just is what it is. It is for this reason that the apparent duality of the world can be understood to be a Non-Duality, then Non-Duality can be known to be just What Is.
