Discrimination
This discriminated and discriminating property of the essential
dimension, and of the Essence of the self, makes it possible for
us to recognize the many forms in which Presence manifests. This
capacity is a reflection of the wisdom of discrimination, of the
nous dimension of Presence. Our understanding is that the capacity
of discrimination exists fundamentally on the ontological dimension
of Presence, and it remains the same property or capacity in other
dimensions but we do not see its reality because we have lost
contact with Presence. In the experience of self-realization,
this property gives the self a capacity for discrimination of
such precision and sharpness that it is inconceivable in the conventional
dimension of experience. (The Point of Existence, pg 473)

Discrimination of mind, body, Essence
The capacity to sense oneself must become so refined that the
individual can discriminate between physical sensation and the
sensation of essential substance. It is not enough that the mind
be quiet. It is also necessary for the body to be sensitive. The
mind can be quiet while the body is deadened. The body has to
be awakened so that the center of sensing, the belly center, can
be activated. The belly center, or what Gurdjieff called the physical
center, is the center of sensing for all parts of the body. It's
deepest function is the subtle sensing, the sensing of essential
Presence, that the Sufis called the organ for touch. (Essence,
pg 130)
