 The time at which the Change came to the fore was that in which the house of Yin [Shang] came to an end and the way of the house of Zhou 周 was rising, that is, the time when King Wen and the tyrant Zhou 紂 were pitted against each other. This is why the hexagram statements of the book so frequently warn against danger. He who is conscious of danger creates peace for himself, he who takes things lightly creates his own downfall. (Xici II:11; WB: 352, with modifications)
