Nourishing the heart is more important to health, but "people's hearts are so clear and disturbing, and people are so quiet and want to get it", so many people are often uneasy and lead to constant distraction. Tao Te Ching can help us improve our wisdom, be less selfish, develop a childlike heart, be merciful, let the Yuan God return to his place, do whatever he wants, and let the spirit converge inward. Only in this way can we nourish our hearts and spirits, and fundamentally play the role of health preservation.
