When physical energies, bodily constituents, and waste products function properly and are in balanced state it is considered healthy. A state of dysfunction or imbalance is unhealthy. Sicknesses arise from three sources: disturbances of the physical energies of this lifetime, ripening of the past karmic imprint, and the combination of physical energies disturbances and past karmic imprint.
If someone loses their outer, inner, and vital life constituents or force (namely the function of the muscles, leaving them unable to eat food and become malnourished) and channels functions, one will certainly die. The aggravation of the physical energies, bodily constituents, and waste products disturbs their balance and destroys each other’s force, causing the deterioration and death of the human body.
The four elements of earth, air, water, and fire form the bodies of sentient beings. Disorders also derive from the four elements. The antidote, called medicines, have the four elements. Thus, the body, disorders, and antidotes are all linked to the same nature.
The innate desire of sentient beings is to avoid suffering and achieve happiness. Hence, people engage in all sorts of activities to find comfort and contentment. Yet without a proper approach, happiness itself can become the cause of suffering. Therefore, every effort must be made to seek guidance to have happiness and comfort in this and future lives.
