Formless
In these realms there are no personal or individual boundaries,
so there is no sense of entity or separate existence. This is
why the dissolution of ego boundaries is the primary requirement
for experiencing them. The experience is beyond the body, and
hence the dichotomy of inside-outside is transcended, and there
is freedom from the restriction of consciousness to a center in
the body. Thus these dimensions are beyond form; it is the body
image that gives us our personal form. The experience is also
beyond the person, beyond personal life and transcending personal
history. (The Pearl Beyond Price, pg 420)

Formless dimensions and seeking
There is no need to make them an object of seeking. When the
student merely leads his or her life fully, metabolizing his or
her experience totally, motivated and guided by the pure love
for the truth, the formless dimensions manifest. The point of
transition to these dimensions arrives when the Personal Essence
is finally integrated and understood. (The Pearl Beyond Price,
pg 420)
