The book has six chapters. The first one introduces the history of Avalokitesvara Bodhisattva in Vietnam, China, and Korea following the tradition of Mahayana Buddhism. It has many simple-to understand stories, but when proceeding to the second, third, fourth, and fifth chapters, readers have to use their intellect to explore them, because the author has incorporated the penetrating hearing method of Avalokitesvara to form this work. The content of this work directly relates to the Surangama Sutra, especially to the twenty-five bodhisattvas presenting their own ways of awakening. The author has skillfully incorporated the Surangama Sutra into the Commentary on Avalokitesvara Bodhisattva, which helps readers to have the opportunity to get acquainted with both works. The author explains emptiness (Skt. sunyata; Pali, sunnata) in detail, making it possible for us to read with great pleasure. With regard to the section on Mahasthamaprapta Bodhisattva practicing the recitation of Amitabha Buddha's name, we find that the author has ingeniously incorporated Pure Land views to introduce the practice to readers here and disseminate this Pure Land idea...
