The legacy of Master Sheng Yen in the Chan Buddhist world can be seen most clearly in the way he revitalized traditional practice while making it intelligible and workable for contemporary people. Drawing on both the Linji and Caodong lineages, he upheld the classical methods of silent illumination and huatou (koan introspection), yet presented them in a structured, step-by-step manner that guided practitioners from ethical living and basic meditation through to deeper Chan insight. This systematization did not dilute the tradition; rather, it clarified the path, allowing lay and monastic practitioners alike to engage rigorously with Chan in the midst of modern conditions. His retreat formats and pedagogical style made demanding practices accessible without sacrificing their depth.

Equally significant is the institutional framework he created to sustain and transmit this vision. Through Dharma Drum Mountain and its related centers, he established a comprehensive network that combined monastic training, lay education, social service, and academic research. Institutions such as the Chung-Hwa Institute of Buddhist Studies and Dharma Drum University embodied his conviction that Chan practice and scholarly inquiry can mutually enrich one another. This integration of contemplative training with formal study helped bridge the gap between traditional monastic culture and modern educational models, ensuring that Chan would not remain confined to ritual or isolated practice.

Master Sheng Yen’s global outreach further extended the reach of Chinese Chan beyond its traditional cultural boundaries. By founding Chan meditation centers and retreat facilities in places such as New York and other international locations, he opened the door for Western practitioners to encounter Chan through clear, carefully translated teachings and intensive retreats. His numerous books and commentaries, written in an accessible yet rigorous style, have served as standard introductions and practical guides for many, offering both historical context and concrete instructions for meditation and daily-life practice. Through these efforts, Chan was presented not as an exotic import, but as a living tradition capable of speaking directly to contemporary concerns.

Another enduring dimension of his legacy lies in the way he linked inner cultivation with social and environmental responsibility. He consistently emphasized that genuine Chan practice must manifest in compassionate action, including education, disaster relief, and the protection of the natural world. This orientation gave rise to a form of socially engaged Buddhism in which meditation, ethical conduct, and care for society and the environment are seen as inseparable. By training a generation of monastic and lay successors who embody these principles, he ensured that his approach to Chan—rooted in tradition yet responsive to the needs of the age—continues to shape communities and practitioners across the globe.
