Diamond Consciousness
The "diamond consciousness," responsible for the diamond
perspective, is like Aurobindo's "supermind" in its
capacity to look through all facets. Cosmic consciousness looks
without facets so it sees everything, all points of view integrated
in one perspective. The diamond consciousness can see all points
of view, including the integrated point of view of cosmic consciousness,
and hold all these perspectives and as equally valid. (The Elixir
of Enlightenment, pg 38)

This Diamond Consciousness is a certain integration of all essential
aspects, which can exist in a dimension that is more refined and
more objective than the usual, most recognizable one. This dimension
is that of the existence of all aspects of Essence as aspects
of understanding. All aspects of Essence function in this dimension
in the service of understanding. For instance, the aspect of compassion
does not exist in this dimension only as the presence of the state
of compassion, but also as the precise understanding of compassion
and its relation to objective understanding. (The Pearl Beyond
Price, pg 187)

In some sense, the Diamond Consciousness is the integration of
the mental faculties-intelligence, discrimination, synthesis,
understanding and so on - into Being, just as the Personal Essence
is the integration of another level of qualities. This aspect
of Essence is the source of true insight, intuition, knowledge
and understanding. It functions through a capacity of simultaneous
analysis and synthesis. Its capacity for analysis is stupendous;
it can move in closer and closer, its perception becoming sharper
and sharper, and its understanding more and more precise, as one
contemplates any subject. It synthesizes all that is available
to the consciousness of the individual, making its analysis ever
more precise. And it can reverse the whole process, using the
insights and perceptions arising from the analysis for greater
synthesis. (The Pearl Beyond Price, pg 188)

Diamond Consciousness is the prototype, on the level of Being,
of the faculty of understanding. The ordinary capacity for understanding
is only a reflection of this capacity. (The Pearl Beyond Price,
pg 188)

Diamond consciousness and understanding
Concepts enable us to reach understanding. Understanding is
nothing but the understanding of concepts. But ultimately, everything
is concepts, and hence understanding is the true revelation
of everything. The essential aspect that functions as understanding,
which we sometimes called the "Diamond Consciousness",
is a manifestation of the absolute reality. Out of Being arises
the capacity for understanding, for the encounter between absolute
reality and the conceptual reality of the mind. (Diamond Heart
Book 3, pg 162)
