The Firmament is conscious physical reality.
It is a mental perspective of Terra Firma.
Terra Firma is the physical world of Earth.
The mental perspective of our physical realm is our reality.
Physical reality is firm & fixed and flows in space & time.
The firmament allows time-space-reality to be consistent & continuous.
In the Bible, God said: “Let there be a firmament in the midst of the waters and let it divide the waters from the waters”.
The waters are a metaphor for mentality or consciousness.
The firma-ment is the state of consciousness between higher (super) consciousness & lower (sub) consciousness.
It is the physical reality between our higher Soul consciousness and our lower dream consciousness.
“And God called the firmament Heaven”.
Heaven on Earth is how conscious reality is designed & meant to be.
