The Qian hexagram symbolizes heaven，which has the attrib¬utes of origination and prosperity, and benignancy and persever¬ance are its true nature. Heaven from the very beginning brings great benefits to all things of creation throughout land but never says anything about it. How great! How great the Qian hexagram is! It is firm and vigorous，just and upright, and pure and quin¬tessential. Its six yang lines change, develop, and reveal exten¬sively nature of all things of creation. It is just as if time rode on the six dragons to drive heaven on its track through different sea¬sons. Clouds float, rain falls, and all things of creation under heaven are in peaceful development.
