Imagine, if you will, we have a collection of material lumps. To begin with, our lumps are randomly scattered about on a table-top, like so many raisins having fallen from a box. Now imagine that we organize these raisins into a square pattern, with each raisin touching its neighbor. We have created a square shaped, larger lump made of raisins. This physical square is material, the pattern of relationships among the individual raisins that create it, is immaterial. The physical square has "emerged" from the relationships among lower-level individual raisins. Said another way, the physical square is a higher level, or layer, of organization arising from the individual raisin lumps that create it. Now, suppose that we have done the same thing in three, rather than two, dimensions. We then would have created a 3-D block. It, too, would be one level up in complexity from the individual lumps that create it. We might use blocks such as these, to build a new, even higher level, more complex, structure... say, maybe a house? This pattern or organization that we call a house emerges from the immaterial relationships among its constituent building blocks. Physical reality is structured this way. It is composed of levels, or layers, with each progressively higher layer being created (emerging) from relationships among the constituents in the immediately-previous, lower layer, each layer becoming increasingly complex along the way.

Any group of lumps greater than a single lump will have a set of relationships among its members. Relationships are immaterial: they have no mass and cannot easily be put in a wheelbarrow. There are numerous other immaterial features of reality. For example, there are immaterial energies and forces. In the classical notion of atoms, there are two building blocks of matter that come with charge, the proton and electron, carrying positive and negative charges, respectively. Because these charged lumps move, they create electromagnetic fields, or forces (EMFs). EMFs are both immaterial and hugely important. We can think of atoms as our basic building lumps. Note that each one of these lumps will also have an immaterial EMF aspect. As we move up the increasingly complex physical layers, we also move up increasingly complex EMF layers. EMFs have outward facing, or objective, properties. That is, they interact with other physical things in publicly observable ways. But EMFs also have inward facing, or subjective, properties, and those private properties reside in the experiential/subjective/mental realm. All EMFs have this experiential dimension/property. That property may be extremely simple or highly complex, it may be conscious or unconscious, but it all belongs to the mental realm/dimension. This is the stuff that our mind is made of.
