It is difficult for beginners, for they perceive matters by means of corporeal boundaries of time, space, change and exchange. However, the authors only used those as signs to point to their upper roots ( Baal Hasulam, The Study of the Ten Sefirot, Vol.1, Part 1, Chap.1).
Here it is necessary to clarify that we are not talking about a material place and its content, as in our world, although we will still imagine this way because we can’t get away from our usual stereotypes.
But at the very least, we need to step back a little from what we have in our minds and think about what place means.
A place is a desire created and filled with some kind of filler. This means that what desire wants is what it is filled with. Only these two substances exist in the universe. Desire is called a place, and filling is called filling or light.
