Dreamless Sleep
You take a journey into the Unmanifested every night when you enter
the phase of deep dreamless sleep. You merge with the Source. You
draw from it the vital energy that sustains you for a while when
you return to the manifested, the world of separate forms. This
energy is much more vital than food: "Man does not live by bread
alone." But in dreamless sleep, you don't go into it consciously.
Although the bodily functions are still operating, "you” no longer
exist in that state. Can you imagine what it would be like to go
into dreamless sleep with full consciousness? It is impossible to
imagine it, because that state has no content.
The Unmanifested does not liberate you until you enter it
consciously. That's why Jesus did not say the truth will make you
free, but rather: "You will know the truth, and the truth will make
you free." This is not a conceptual truth. It is the truth of
eternal life beyond form, which is known directly or not at all.
But don' t attempt to stay conscious in dreamless sleep. It is
highly unlikely that you will succeed. At most, you may remain
conscious during the dream phase, but not beyond that. This is
called lucid dreaming, which may be interesting and fascinating,
but it is not liberating.
So use your inner body as a portal through which you enter the
Unmanifested, and keep that portal open so that you stay connected
with the Source at all times. It makes no difference, as far as the
inner body is concerned, whether your outer physical body is old or
young, frail or strong. The inner body is timeless. If you are not
yet able to feel the inner body, use one of the other portals,
although ultimately they are all one. Some I have spoken about at
length already, but I'll mention them again briefly here.

What Eckhart said here is roughly there. Except that Thusness
implies that it is not necessary or impossible to enter dreamless
sleep 'consciously' (ironically Eckhart's second paragraph's first
sentence contradicts his first paragraph), which I believe would
equate to a sense of Witnessing presence. This is not the same as
deep dreamless sleep where even the sense of Witnessing presence
dissolves into complete non dual absorption.
