Buddhism under Mao shows what kind of a problem Buddhism presented to the Chinese Communists and how they solved it. Relying largely on materials from the Mainland press, Holmes Welch has made what is probably the most detailed study so far available of the fate of a world religion in a Communist country. He describes how Buddhist institutions were controlled, protected, utilized, and suppressed; and explains why the larger needs of foreign and domestic policy dictated the Communists’ approach to the institutions. Over eighty photographs illustrate the activities of monks, laymen, and foreign visitors.

Welch worked for over a decade on the trilogy here completed. The preceding volumes, The Practice of Chinese Buddhism, 1900–1950 and The Buddhist Revival in China, dealt with Buddhism in the years before the Communist victory. Buddhism under Mao ends with a discussion of the possibility of the survival of certain elements of Buddhism in new forms.

Of all the world's major religions, Chinese Buddhism has probably experienced the most traumatic modernization. The establishment of a communist state quickly emerged from the self-contained Manchu Empire. The consequences are described in this book. Holmes Welch offers the first detailed account of the careers of recent Buddhist leaders and of the diverse organization they started. Eighteen Chinese Buddhist associations are identified as the author traces the struggle for national leadership. The role of T'ai-hsü, the leader best known to Western readers but not, it is shown, among Buddhists, is given a controversial reassessment.

After examining the main features of the revival, Welch puts them into a larger political framework. In the process, he offers copious evidence that our picture of Chinese Buddhism has been distorted. What has been termed a "revival" was actually a secular reorientation. The author's conclusion is that this secularization, vigorous as it was, in reality foreshadowed the decline of Chinese Buddhism as a living religion.

Based partly on unpublished documents and oral information obtained from monks who headed major monasteries on mainland China, Holmes Welch presents a detailed description of the modern practice of Chinese Buddhism. Focusing on the actual rather than the theoretical observances of the religion, he gives an exhaustive account of the monastic system and the style of life of both monk and layman. His study makes new information available for the Western reader and calls into question the whole concept of the moribund state of Chinese Buddhism.
