Prejudice
When we use the word "prejudice," we don't mean just
its common restricted usage: having fixed ideas about a particular
group, race, religion, or set of beliefs. Prejudice, as we are
using it, means anything that distorts the objective perception
of reality. In other words we consider prejudice anything that
determines the attitude of a person that is not totally in accord
with what actually is. (Work on the Superego, pg 1)

Fixed, rigid, and inaccurate impressions constrain the soul's
receptivity to her potential to be prejudiced exclusively toward
the elements of this potential that are consonant with the rigidity,
fixation, and falseness. The soul has the potential to be false,
to manifest rigid and fixed forms, opaqueness, dullness, and
darkness. (Inner Journey Home)

One cannot look at oneself with any prejudice, opinion, attitude,
expectation or assumptions without losing objectivity. One must
approach the experience wanting nothing and expecting nothing.
The only motivation that can work is the innate and spontaneous
love of truth for its own sake. If one wants truth because it
feels good or is going to lead to a good result, or if one wants
the truth because it will relieve one's suffering, then one is
already prejudiced and cannot be objective. So for there to be
absorption, absolute objectivity is required. (The Pearl Beyond
