The perfection of discriminating awareness occurs when flights of fancy, intellectual conceptualization, and all thought dissolve into an awareness of the skillful means employed in the other five perfections.
This understanding cannot be separated from the object of perception, which is seen in detail in its luminous reality. The screen of preconceptions and irrelevant associations is torn down by concentration accompanied by a critical dialectic.
All theories about the universe are destroyed by the Madhyamika dialectic that reduces to absurdity each successive machination of the intellect as it is driven from one untenable position to another.
Finally, it is forced to let go, allowing the innate understanding of every perception to attune the enlightened mind to the harmony of the total situation.
