Process of Understanding
For the process of understanding to happen, three elements need
to be there at the same time. The element of disidentification
is one of them, involvement is another. The third element is the
quality of allowing. These elements can be there when there is
harmony among the three centers -- the belly center, the chest
center, and the head center. When there is this harmony, it is
possible to experience fully, to allow, and to disidentify. (Diamond
Heart Book 3, pg 73)

Understanding and Grace
All of his means that we don't actually do anything in the process
of understanding. What needs to happen is just an awareness of
the fact that you're resisting an understanding of the process
of resistance. When you understand it, your interest in resistance
stops. All you can do is allow that to happen; the rest is not
up to you. The rest is up to Essence. That's why it is sometimes
called grace. Grace can descend and dissolve you. It can make
you part of it. But you cannot let go, you cannot surrender, you
cannot accept. You can only see that you are rejecting, that you're
not surrendering, that you're not letting go. Then you are seeing
the activity of the ego. (Diamond Heart Book 3, pg 183)

Understanding and meditation
Understanding is actually a kind of meditation; it is not a seeking,
not a figuring out, not an attempt to find information outside
oneself. It is spontaneous, and effortless insight. To engage
in the process of understanding does not involve doing anything.
If there is anything to be done, it is a matter of attention –
just being sure you are present. When you are present in your
being, the insights will arise naturally and understanding will
arise naturally. (Diamond Heart Book 4, pg 28)
