Prajna (Wisdom) — The Sixth Paramita
Prajna is not knowledge accumulated but seeing directly — the sword that cuts through conceptual elaboration. The Heart Sutra's 'form is emptiness, emptiness is form' is prajna's most compressed statement. Hex 20 (Contemplation) is wind over earth: the ancient kings used this to inspect the regions and instruct the people. The view from the tower. But prajna differs from ordinary contemplation in that it sees the tower itself as empty. The I-Ching's Hex 20 describes seeing and being seen — 'contemplation of the divine meaning underlying the workings of the universe.' Prajna is exactly this contemplation turned inward until the contemplator dissolves. The sixth paramita completes and transforms all the others: generosity without prajna is still self-serving, patience without prajna is still endurance of a self.
