Prajna is the fundamental noetic principle whereby an apprehension of the whole becomes possible.

Prajna is a unifying principle. It does this not by going over each individual unit as belonging to an integrated whole, but by apprehending the latter at one glance, as it were. While the whole is thus apprehended, the parts do not escape from entering into this vision by Prajna. [Even the smallest] parts are united in the whole to become significant, and this unification is the doing of Prajna-intuition.
