Joy
Joy: The force and consciousness behind curiosity. This is a
very subtle aspect to understand, and a very difficult state to
realize. It is, just as Freud thought, the happiness that results
from wish fulfillment. Whenever there is an unfulfilled wish Joy
closes and disappears. This means that it becomes permanently
realized only when there are no unconscious wishes. So, more objectively

no lasting fulfillment as long as there is any aspect of Being

What does joy have to do with the pain or no pain? Joy is different
from pleasure in the sense that joy has nothing to do with pain

possible for it to be there, allow it. Joy has to do with openness
in the moment, with not choosing one thing over another. When
there is no prejudice about what should happen, there is joy.
Joy is openness to experience. There is no striving. Joy is not
the result of anything. If you are yourself, there is joy. If
you are accepting and are open to your experience, if you're being
yourself, you are naturally joyful because you are the source
of the joy. (Diamond Heart Book 3, pg 86)

So openness is the basis of inquiry, but love expressed as curiosity
specifically invites the Diamond Guidance. This active edge of
openness is needed for the truth to be revealed. Then there is
joy, curiosity, a happy excitement to find out. The not-knowing
becomes the beginning of adventure. And because you don’t
know, it is more exciting. Joy is in the whole process, and the
excitement of life intensifies. The soul is turned on to exploring
the mystery, and it is curiosity that engages… (Spacecruiser
