The Diverse Health Preservation Literature and Ideas in the Sanyuan Canzan Yanshou Shu

The Sanyuan Canzan Yanshou Shu 三元參贊延壽書, compiled by Li Pengfei during the Yuan dynasty, is a comprehensive collection of the essence of earlier health preservation literature. Recently, the Jianwen first-year (1399) re-engraved edition by Liu Yuanran 劉淵然 (1351–1432) has emerged, which is currently housed in the Imperial Household Agency Library in Japan. It has challenged the prevailing consensus in China that the edition (1445) in the Daozang 道藏 is the earliest version. This discovery not only enriches our understanding of the text’s historical dissemination but also highlights the international appreciation and preservation of Chinese traditional medical and health knowledge. Upon meticulous examination, the various editions of this text can be systematically classified into two distinct lineages: Yanshou Canzan 延壽參贊 and Canzan Yanshou 參贊延壽. The latter lineage is notably more comprehensive, with the Wanli 萬曆 edition serving as a prime exemplar of this expanded scope. Li Pengfei primarily drew upon the Yangsheng Leizuan 養生類纂 as the foundational text for his work, skillfully integrating a wealth of Daoism and medical scriptures. He adeptly restructured the content by employing the conceptual framework of three primes (sanyuan 三元), incorporating the health preservation philosophies of Confucianism and Buddhism, thereby transforming it into a more systematic and diverse Daoism scripture dedicated to health preservation. The book eloquently advocates for health-preserving philosophies centered around the principle of not diminishing (busun 不損) primordial pneuma (yuanqi 元氣), extending life through three primes, and prolonging life through the virtue of yin (yinde 陰德). These ideas emphasize a human-centered approach, focusing on preserving the primordial pneuma as the foundation and employing both loss prevention and supplementation as dual pathways. It aims to achieve a state of health preservation where there is unity of man with heaven (tianren heyi 天人合一) and a harmonious balance of yin and yang energies (yinyang qihe 陰陽氣和).
