Asha is the central concept of Zoroastrianism — truth, righteousness, the order that holds the cosmos together. It is cognate with Vedic Rta (cosmic law) and resonates with Egyptian Ma'at: not a commandment from outside but the grain of reality itself. Hex 1 (The Creative) is Asha as cosmic principle: pure yang, the generative order that precedes all manifestation. Hex 15 (Modesty) is Asha as ethical practice: the mountain hidden within the earth, power that aligns itself with the structure of things rather than imposing upon them. Every line of Hex 15 is favorable — the I-Ching's way of saying that alignment with the real order always succeeds. The Gathas say it differently: 'Asha is the best good.' Not a good among goods. The best. The structural one.
