127- Progression of Humankind’s thought process
These three dimensions are for a mentally infantile human and not for humans who have progressed mentally.
For instance, a clairvoyant person standing outside a house is told to measure its living room's height. Even though this individual is outside the building, he sees beyond the walls. Moreover, he sees a spider's web under the ceiling.
Considering the ceiling as the barricade, he intends to measure the height from the floor's surface to this barricade, but why should he not measure from the surface to the spider web and from the spider web to the ceiling? That spider web (even though diminutive) is a barricade itself.
Now I say that to people with clairvoyance ability, the ceiling is like that spider web. It holds no tangible value and cannot be considered a boundary or border for measurement since they see beyond any barrier. As they go higher (as people use the term higher), they can see even higher.
