How to Avoid Illness

Preventive care, health preservation, nurturing life, and maintaining well-being—these concepts all encompass the principles and knowledge of how to avoid getting sick. Illness arises from going against the natural order of heaven, earth, yin and yang, and the four seasons. Therefore, by changing one's lifestyle to align with these natural rhythms, one can follow the best path to health and longevity.

Illness often results from overindulgence, so the core principle of Daoist health wisdom is encapsulated in the saying: "Managing human affairs and serving heaven with frugality is key." In simpler terms, this means avoiding wasteful habits and embracing a lifestyle of frugality and conservation.

Once one begins to understand the importance of preserving vital energy, they gradually come to comprehend the principle of harmony between heaven and humanity. This understanding leads to the realization of the importance of moderation, not just in spending but also in all aspects of life.

By following this approach, the body can align with the natural order of the universe, reaping the greatest benefits at the lowest cost. By nurturing the body's yin and yang with the balance of the natural world, the body's positive energy remains abundant, preventing negative energy from taking hold. As the saying goes, "When positive energy prevails, negative energy cannot penetrate."

The higher level of health preservation is described as "tranquility and emptiness, where true energy follows; with the spirit maintained internally, illness cannot arise." This advanced practice is difficult for most people to master. "Tranquility and emptiness" refers to maintaining an undisturbed mind, unaffected by the chaos of the external world, like a mirror reflecting the world without attachment. 

This is the essence of the sage's wisdom. When the mind is free from worries, true energy flows smoothly. "Maintaining the spirit internally" means not only practicing frugality but also mastering the art of preservation.

The more positive energy one accumulates, the further they distance themselves from illness.
