To make the concept of 3 realms and 3 layers more clear, I provided out with an example.
Imagine a lump of gold. In W1, it is a completely unknown entity. No one knows what matter or energy in core. Physics can only describe it with some mathematical equations. This lump is a changing arrangement of small particles that we observe and measure in order to form a W2 model of it. In other words, the W1 entity leaves some W2 impressions (L1, L2, and L3) inside our mind. The model we make can have different dimensions. We partly organized these impressions into the science of gold. In L2 gold is a metal in Mendeleev’s table with some properties that experience and experiments made them known. In L3, the conventions, traditions, and the way people regard gold gives meaning to it (we think in a certain way about gold). We regard it as something valuable, lovable, worthless, or disgusting depending on our way of our thinking, and in W3, we feel accordingly.
The way we feel about gold is closely related to its visual beauty, its unique functionality, and its cultural meaning.
A lot of meanings (W2 compositions) through symbolism are integrated and synthesized to create our ultimate mixed feeling about the gold. Meanings such as being unique, rare, valuable, or sought after (as well as having unique physical properties) make god a symbol of superiority and control.
What you (or the feeler) feels about gold is far from what really gold is in W1. This shows the pitiful condition of humans. What you feel about things is a construct far away from their W1 essence. In fact, W1 is completely unknown, and L2 is full of uncertain hypotheses that we can rely on them based on the principals of uniformity, and our pragmatic inductions and deductions. Moreover, our L3 is formed by the quality and quantity of our hardware and software that many things in many different levels affect its lenses, and no two individual have the same lenses in L3. And finally W3 is the ultimate magic where all these composition are felt. Human condition is full of unknown, uncertainty, and mystery. We should find our way backward from W3 toward W1.
