‘心灯’ (xīn dēng) literally means ‘heart lamp’ or ‘inner lamp’. It is a poetic, metaphorical term rooted in Buddhist and Daoist traditions, symbolizing one’s innate spiritual awareness, wisdom, or moral clarity—the inner light that guides understanding and compassion even in darkness or confusion. The character 心 (xīn) means ‘heart’ or ‘mind’, representing the seat of consciousness and emotion; 灯 (dēng) means ‘lamp’ or ‘light’, evoking illumination, insight, and awakening.

This term appears frequently in classical poetry, meditation teachings, and inspirational speeches. It is not used in everyday casual speech but carries deep emotional and philosophical weight—often invoked to encourage self-reflection, resilience, or ethical courage. Unlike physical lamps, 心灯 cannot be lit by others; it must be nurtured through sincerity, mindfulness, and kindness. It implies that true guidance comes from within, not from external authority or circumstance.
