Enlightenment
Enlightenment does not involve simply the perception that the
person is only a concept. It means that all conceptualization
is ended; all images and representations in the mind, whether
conscious, preconscious or unconscious, are eliminated, or at
least not identified with. When this profound stillness of the
mind is achieved, it is asserted; true reality is perceived, not
by an entity which is a separate individual. The experience is
one of unqualified Being, wordless existence, infinite and eternal.
(The Pearl Beyond Price, pg 27)

Actually, there is no universal or agreed upon definition, or
even understanding, of the concept of enlightenment. Different
traditions use the word differently. Different teachers refer
to different realities when they use it. And most people have
not the vaguest idea what they are talking about when referring
to enlightenment. Sometimes enlightenment means the attainment
of a certain stage of Being. Sometimes it refers to a certain
insight, perception or understanding. Sometimes it refers to a
certain stage of inner development, usually the final stage, which
becomes problematic since different traditions take different
conditions to be the final stage. Sometimes it signifies the transcendence
of ego, other times the death of ego, still other times the transformation
of ego... The concept can be useful only in a teaching that defines
it very specifically. But we cannot use the concept assuming it
means the same thing in all teachings or traditions. (The Pearl
Beyond Price, pg 182)

Some people think that enlightenment is when all your problems
end. Enlightenment is really when your problems start. Enlightenment
is partly the realization that you are responsible in your life,
that your life is completely your responsibility, and you are
the one who really has to live it. You have to live life the way
you know you ought to do it. It’s not going to just happen.
