For centuries, the concept of the soul has largely remained within the domain of religion, as modern science has yet to confirm its existence. Nonetheless, numerous spiritual experiences and documented cases indicate that the soul constitutes a vital aspect of human life. It profoundly influences physical health and mental well-being beyond current scientific understanding. This paper examines the condition known as “Incomplete Soul (魂魄不齐)”—a state of partial soul loss unrecognized by modern medicine—through the teachings of Dharma Master Jun Hong Lu and the Guan Yin Citta Dharma Door. Drawing upon Master Lu’s insights and real-life case studies, we explored how soul loss manifests through symptoms such as distraction, confusion, and emotional instability, and how these conditions can be alleviated through Dharma-based practices, including the recitation of Buddhist scriptures, the offering of Little Houses to the karmic creditors, and the “calling back the soul (叫魂)” ritual. The evidence presented underscores that the integrity of the soul is fundamental to human health. Dharma thus offers a profound, scientific framework for understanding the spiritual roots of illness, providing a pathway to healing beyond the boundaries of conventional medicine.
