'For the most part, both good and bad arise from habits. Being circumspect in taking care of your health and making an effort to support it will create good habits. If you avoid laziness, exert yourself in the field of health, and put into practice the Way of Nurturing Life and other tips on well being, you will become accustomed to following this path. The results will be beneficial and constant and you will live without pain.
If you are not circumspect and create unhealthful and bad habits, when you do exert yourself to improve your health, it will be painful and hard to bear.'
