Huayan Jing (Avata saka Sūtra) is one of the most influential sutras in Chinese Buddhism. The cosmic vision of infinite realms mutually containing each other described in this text was the theoretical foundation for the Huayan school of Chinese Buddhism. Therefore, this work has been highly esteemed by Chinese Buddhist masters and lay people. This paper takes Ven. Hiu-wan (1912-2004) as an example to verify the deep influences of Huayan Jing on her Buddhist practices and contributions. Mainly by analyzing the quotations and interpretations of Huayan Jing in her early works, Dao-yu sui-yue (Times and seasons in Hong Kong islands), Huan-yu zhou-xing san-ji (Random notes of the trip around the world), Si-shi san-ji (Random notes of the four seasons), and Jing-yuan sui-bi (Writings of rambling thoughts in Jing-yuan monastery), the author brings forth the following conclusions: 1. The teachings in Huayan Jing had been the golden rule of Ven. Hiu-wan’s moral conducts. 2. The teachings in Huayan Jing had been assisting Ven. Hiu-wan to deepen her insight while practicing meditation. 3. The teachings in Huayan Jing had been strongly inspiring Ven. Hiu-wan to take the great vow of Bodhisattva.
