In the mundane world prosperity and abundance are defined as having more than enough. But more than enough of what? Are we really prosperous if we have a large pile of rocks in our front yard? If the large pile of rocks were diamonds, would that change our view?
Here is the crux of the matter and where perception fits in. First, we have to define what our values are. What is the difference between having 100 pebbles and 100 ten-carat diamonds? What makes a diamond valuable and a pebble less so?
This, of course, is an extreme example but used deliberately to prove a point. Whatever the material things are in our lives, they are perceived according to some arbitrary standard.
This is the basis of our perception. It is a judgment based on some learned, and probably long forgotten rule. It is our emotional reaction towards a neutral event or symbol which someone along the line has convinced us is valuable or worthless.
