Sunyata (Emptiness) — The Heart of Mahayana
Sunyata is the most misunderstood concept in Buddhism. It does not mean nothingness but the absence of inherent, independent existence in all phenomena. Everything arises in dependence on conditions; nothing exists from its own side. Nagarjuna's Mulamadhyamakakarika demonstrates this through rigorous dialectic. Hex 2 (The Receptive) is pure yin — earth over earth, openness without content, the space that receives all forms without being any of them. The I-Ching says: 'The mare wanders without bound.' Emptiness is not a void but an infinite capacity. Hex 2 is not passive — it is the ground that makes all growth possible. Sunyata functions identically: emptiness is not the negation of phenomena but their condition. Form is emptiness; emptiness is form. The Receptive does not lack the Creative — it enables it.
