When the Halls of Amenti was sealed off to human
lineage, it
was because the DNA of Root Race 3 and Root Race 4 had
mutations that could have destroyed the planet Earth and Tara.
So the portal between Earth and Tara was blocked
off until that DNA mutation was cleared up. The DNA codes that
would have allowed for DNA strands 7 to 12 to assemble were shut
down.
As a result there was an energetic block between the physical
body and the etheric body. "This created perception of
duality
between consciousness and body for those baring this genetic
configuration." (page 19, Voyagers vol.2. 2nd edition)
"Human consciousness lost awareness of its relationship to
Earth and the higher dimensions and its species evolutionary
memory..." (pg 21, Voyagers vol 2, 2nd edition)
