Mind
In ordinary usage, the word "mind" refers to thoughts,
the thinking process, or the thinking apparatus. But there are
other usages: in the East, for example, "mind" includes
more than just the thinking sphere. And here in the West as well,
the word often has a larger meaning. In fact, most of the depth
psychologies and the social sciences in general, use the term
"mind "to include all inner experience. The mind is
then taken to be the field or sphere of our thoughts, images,
feelings, emotions, sensations, and perceptions, plus the apparatus
or agent that deals with all these impressions. This "mind"
is connected not only to the brain, but to the totality of the
nervous system. Here, we will use the term "mind" in
this larger, more inclusive sense. We will also be open to modifications
or extensions of this definition. (The Void, pg 1)

Mind and Being
This is an important difference between the mind and Being. The
mind can absorb and identify with any psychic material it believes
to be true. It does not have the capacity, on its own, to discern
what is objective truth and what is not. In other words, the mind
can be deceived, even by itself. Being, on the other hand, is
pure reality. It is the actual stuff and consciousness of truth,
and cannot be deceived. It does not try not to be deceived; it
is simply truth by its nature, a self-conscious medium made of
pure sensitivity. (The Pearl Beyond Price, pg 163)

Mind and beyond mind
And if I want to penetrate beyond my mind and see what is there,
it is a mystery. It is unknowable, completely, one hundred percent
unknowable. It is so unknowable that the moment you begin to get
a glimpse of it, your mind is blown to smithereens. You realize
that your mind lays a kind of curtain over things, a veil, a colored
sheet with drawings on it that overlays our reality and says,
“That is reality”. But the reality is beyond that:
you open that curtain, open the window and it is unknowable. If
you truly look, you do not even know you are looking, and you
disappear. Your mind is there, but nobody is looking. The reality
is there and you do not say there is mind or there is reality.
And then, what you perceive, although it is mysterious, it is
unknowable, we give it a name. We call it truth, we call God,
we call it reality. These are just words, words to refer to the
unknowable, to the unknown, to the mystery. (Diamond Heart Book
4, pg 263)

Mind and concepts
As the mind understands more and more, it reaches a place where
it knows that not everything can be known conceptually. It knows
definitely, absolutely, that something is there, but the mind,
itself, cannot know it. Beingness, however, knows itself, and
knows itself not by a reflection on itself, but just by being
it. (Diamond Heart Book 3, pg 164)

Mind and consciousness
So we're seeing here another meaning of mind, which is pure consciousness.
There is perception, but that perception is not anything but the
perceptivity itself. At this point we go into mind, not in a sense
of it being just space, but of it being perception, consciousness.
We see that we always have that consciousness. Every person, and
every living thing, has this consciousness. In our everyday experience,
there is always a consciousness of something; we never know consciousness
by itself. There is always consciousness of the rug, my foot,
my mind. The consciousness and the content of consciousness are
never separate. The consciousness is always taken to be the content
of consciousness, because that is how we operate with our limited
consciousness. We never see consciousness itself, in its purity.
(Diamond Heart Book 2, pg 19)

Mind and essential development
There is an inner consistency and order for the process of essential
development. There is no need for the mind to direct the process.
In fact, directing the process by the mind can only lead to difficulty,
for the mind does not know. Commitment to the truth is sufficient
for the process to unfold. When the essential aspects are discovered
and freed, when the incomparable pearl is realized, the process
spontaneously unfolds in the direction of the instincts and ultimately
of the survival issue. (Essence, pg 174)

Mind and heart
The nature of the mind is emptiness, and the subtle consciousness
that perceives that emptiness is the heart of the mind. But this
relationship of the heart to the mind is even more complex. There
is also the mind of the heart, the consciousness of the heart,
the knowingness of the heart, the curiosity of the heart, and
the sensitivity of the heart. The heart is seen as the sensitive
organ, the knowing organ. It is conscious and perceptive. The
heart is sometimes called the mind because the heart is the source
of the heart of the mind. In this way, one could also say the
mind is the mind of the heart. But their unity goes even further
than the mind of the heart or the heart of the mind. They are
the same. At the level of understanding the mind as a subtle consciousness,
as an aspect of Essence, there is no heart and no mind, there
is only one thing. It is experienced as one consciousness with
no separation of the centers. (Diamond Heart Book 2, pg 24)

Mind and suffering
To throw away your mind means to throw away what you think you
are, what you think the world is, and what you think is there,
what is not there, what is good, what is not good – to throw
it away, all of it. Otherwise, what you will perceive, and what
you will be experiencing, is nothing but parts of your mind, a
continuation of the past coming from your own memory. When I say
the world is old, or what we see is old, I do not mean old in
the sense that it has grown in time. I mean old in the sense that
it has stopped growing. It is dead in its old form, the way you
constructed it years and years ago. The mind perpetuates ghosts,
dead things; there is no life in them. They are not light –
they’re heavy, dark, dank, old, and musty. They are stale.
In that dark, old, dank world, you suffer. The suffering is felt
mostly because we still believe that old, dark, dead world to
be reality, and we live as if it is reality, wanting one part
of it, not wanting another part of it, putting part of it against
another part of it. You are putting this dead body against another
dead body, not liking this dead thing, liking the other dead thing.
When you want something because you have experienced it in the
past, what you are wanting is a corpse. It is already dead. (Diamond
Heart Book 4, pg 142)
