Impeccability
To be impeccable at that moment is to do all that you can do
to pay attention, to use whatever you have learned, especially
at those times when you know you have a tendency not to pay attention.
Your knowledge is not perfect, not complete, but you use what
you know, the best techniques you have, the best attitude you
have, the best understanding you have, and apply it right then.
(Diamond Heart Book 1, pg 214)

It is not to be perfect but to do your best, to act according
to all the wisdom, all the understanding, all the experience,
all the awareness, all the will that you have. As you confront
your indulgences, you will see that to continue to be really impeccable
and not succumb to your indulgences will mean letting go of all
kinds of things. The way of impeccability can be taken as a path
on its own. You could attempt to be impeccable all the time and
all your indulgences would arise, which would reveal all your
attachments. Impeccability means letting go of those attachments.
The way of the impeccable warrior is a way complete in itself,
is a path to a certain knowledge. In our Work here, we’re
not taking that path by itself, but we’re using it. We’re
taking that attitude as an aid. (Diamond Heart Book 1, pg 218)

Impeccability and action
To act impeccably means to act with certainty. You cannot act
impeccably when you are not sure of yourself. You know it is the
best thing, even if you know that it is not perfect, but you do
it with certainty. You’re learning to defend against your
superego. You are not completely sure what this means, but you
know something, and what you know is the best you know, and you
do this as if you are certain. And this is what you do until you
learn something else. In time, this will evolve and develop into
what we call true certainty – essential certainty. Choosing
to be an impeccable warrior means choosing to be a person, choosing
to be a responsible adult, instead of being your mother’s
baby. There is dignity in it; you are your own person, your life
is your responsibility and you always have the choice to do your
best. Impeccability can be in action, in feeling, in thinking.
Impeccability can be in terms of the will, in terms of the mind,
in terms of the heart. (Diamond Heart Book 1, pg 219)

Impeccability and superego
When you’re learning to defend against your superego, you
really need to be an impeccable warrior. You can’t do it
in a haphazard way. You can’t do it at one time and not
at another, a little bit now, a little bit later. It won’t
work. You have to do it constantly, all the time, impeccably.
That means if you really want to learn about defending against
your superego, you make it your number one aim …you are
always aware of defending yourself against your superego and you
do your best. (Diamond Heart Book 1, pg 216)

Impeccability and truth
To be an impeccable warrior, you do your tasks impeccably and
your task is to be impeccable. That’s it. You do your best.
After a while, you are impeccable for the sake of impeccability
itself. I’ve talked about it in terms of a path leading
someplace, but it is actually what we’re going toward. It’s
both the means and the end. When you are really impeccable, that’s
it. It’s not as if you’re looking for truth because
truth will lead you someplace, to something else. No. You are
dedicated to the truth because the truth is truth. It is the same
thing with impeccability. (Diamond Heart Book 1, pg 221)
