*7.)  Because people do not purify
their consciousness before sleeping,

a.)  they are mostly holding negative,
destructive & selfish: thoughts and
lower desires, before sleep,

b.)  so instead of ascending to 5th
Kingdom, they descend to lower
spheres corresponding to their
thoughts.
Inner Life & Sleep


5.)  “For almost half their lives
people entrust themselves to an
invisible world.
 It is necessary to
purify one's consciousness before
entrance into the sacred Gates.
Thought about the Higher World,
thought about the Guardians, already
lights up the drooping consciousness;
hence, there may be more desirable
meetings, and attacks may be warded
off. Only the heart's thought about the
Higher World provides an impenetrable
armor.” (Aum, 71.)


6.)  “Science gives little attention to the
significance of sleep—this existence in
the Subtle World. Is not a strong unity
with the Hierarchy needed when we are
at the threshold of something unknown
to our habitual consciousness?
Consider that almost half of life
passes beyond earthly existence
!”  
(Heart, 92.)
