At the heart of Master Sheng Yen’s teaching lies the insight into no-self and emptiness: that neither persons nor phenomena possess a fixed, permanent essence, and that clinging to such an essence is the root of suffering. From this perspective, Chan is not an abstract philosophy but a direct, experiential path to seeing through delusion and loosening attachment. This realization is not meant to remain a rarefied insight; it naturally gives rise to flexibility of mind, reduction of suffering, and the flowering of compassion. Wisdom and compassion, in his presentation, are two inseparable aspects of one awakened mind.

Equally central is the insistence that Chan practice must be fully integrated with ordinary life. Meditation is important—especially methods such as silent illumination and huatou—but it is never an end in itself. Ethical conduct, responsibility in relationships, and engagement with work and society are treated as essential fields of cultivation rather than distractions from practice. In this way, daily responsibilities become the arena in which insight into emptiness is tested, refined, and embodied.

Master Sheng Yen also emphasized a gradual, systematic approach to cultivation. Rather than relying solely on the ideal of sudden enlightenment, he stressed step-by-step training in mindfulness, concentration, and ethical discipline to prepare the ground for deep insight. After such insight, continued practice remains necessary so that understanding matures into stable character and conduct. This balanced view allows practitioners to value both the transformative power of awakening and the patient work of ongoing refinement.

A further dimension of his teaching is the call to protect both the natural and the spiritual environment. Social and ecological problems are traced back to untrained, self-centered minds dominated by greed, anger, and ignorance. Purifying the mind through Chan practice thus becomes inseparable from caring for the world, since recognizing the interconnectedness of all life naturally expresses itself as environmental stewardship and compassionate action. In this sense, his teaching motto about facing reality, accepting responsibility, enjoying life, and not taking anything as a problem encapsulates a Chan spirit that is at once profound in insight and thoroughly practical in application.
