"The "Chao Lun: The Treatises of Seng-Chao", is the main scripture of the first period of Chinese Buddhism (about A.D. 300-700) before Dhyana-Buddhism absorbed all other interests (A.D. 700-1100). The Author believes that the two periods are connected and that in Dhyana-Buddhism the earlier thinking emerged cleansed from the traces of its Indian origin. Seng-Chao interpreted Mahayana, Hui-Neng and Shien-Hui re-thought it. The position of the Author is unusual and might be contested. But after a life-time given to the study of Chinese-Buddhism and the Chao-Lun in particular he has the right to be heard."
