Form is the foundation of life. Therefore, keeping in good health lies in preserving shape, supplementing shape lies in nourishing qi, nourishing qi lies in calming the heart, calming the heart lies in sincerity, and nourishing the heart lies in perfection, which is not enough for keeping in good health.

People's external body is the foundation of life, so we should keep healthy. The key to making the body full of vitality lies in regulating the breath, and the key to nourishing the spirit lies in a peaceful mind. The key to peace of mind lies in moral honesty, and the key to cultivating sincerity lies in exerting one's own nature. So if you can't fully release your nature, you can't keep in good health.

Translated by myself for reference.
