Awakening
The manifestation of Pure Being is the experience
of awakening. One merely wakes up and realizes one's pure nature.
It is as if one is usually dreaming, but is taking the dream to
be reality. Then he wakes up and spontaneously realizes the true
state of affairs... There is no sense of discontinuity of experience
in awakening. It is not that something that was not there is now
manifest. It is more like becoming cognizant of the presence of
something that has always been there, and known to be there, but
ignored. (The Pearl Beyond Price, pg 446)

The soul informed by the ego is asleep. This is why enlightenment
is called awakening -- your soul wakes up to what is really here.
Many people believe that this awakening happens automatically the
moment you have an experience of Being. Some parts of your soul
may wake up, but the soul is very deeply imprinted by the egoic
sense of inferiority, and this depth of the soul does not awaken
easily or rapidly. When your awakening does approach this level,
the first thing you wake up to is this sense of inferiority. The
most evident manifestation of the soul being asleep is one's unshakable
conviction in conventional or consensus reality, and in the content
of one's overall social conditioning. Regardless of what profound
experiences of Being you may have had and how objectively you may
have seen reality, when you get up off your meditation cushion or
leave a meeting with your teacher, you act, feel, and behave as
if reality is the world you learned from your mother. When you do
this, you are expressing the asleepness of your soul. (Facets of
Unity, pg 222)

Awakening and brilliancy
This experience of awakening operates on two dimensions simultaneously.
First is the psychological one. To be awake means you are literally
awake—like having awakened from long sleep, or from illusions,
from dreams, from all the sufferings of ignorance. This is the
psychological awakening: Now you see the truth and wake up from
the lies and the ignorance that you have been living in. It also
means you wake up to your true nature: You now see what and who
you are, instead of what you thought you were. The second sense
of awakening is phenomenological. It is the sense of being awake,
clear, and bright, as if you just woke up. Suddenly your head
is above the clouds and you start seeing. So this awakening is
not only a matter of awakening to some truth; it is a certain
state of Being. It is being awake—you actually and literally
experience yourself as a bright and brilliant presence. You have
not only awakened, but you are the awakeness, you are the awake
and brilliant presence. (Essence of Intelligence, pg 338)

That is what Brilliancy does when it explodes in the brain.
When it explodes in the perceptual centers, it is a sense of
waking up in Essence. We’ve seen Brilliancy in many ways—as
intelligence, as synthesis, as completeness, and so on—but
now we are seeing it in terms of actual enlightenment. You are
awake not only because you have an insight about something, but
also by the fact of being the state of awakeness. You feel as
if you were a light bulb. You are actually awake, and everything
is awake. All your senses are bright and open and clear. You
are an awakeness that is awake to everything. This awakeness
is also you, your very beingness, the very substance of your
soul. (Essence of Intelligence, pg 339)

What do you become clear and awakened to? Your nature, to what
is you. You become a light, but the light—by becoming light—becomes
awakened to itself as a light. You become a light unto yourself.
What you awaken to, which is a specific effect of the brilliant
drink, is that your nature itself is pure preciousness itself,
the utmost preciousness that there can be. So you realize that
your nature is not only luminous and brilliant intelligence,
but that it is precious. You see and appreciate now the sense
of preciousness of Being, your essence, the substance of your
consciousness. It is this preciousness that awakens, it is this
preciousness that wakes you up, and it is this preciousness that
you awake to. This is the preciousness of Being, of Essence,
and the preciousness of what a human being is. (Essence of Intelligence,
pg 339)
