As per this principle, when the internal conditions of the body are hygienic, which implies that the eliminatory organs are performing their daily functions under ideal or almost ideal conditions, and the body is free from any obstructions, such as the deposition of foreign matter, the practitioner experiences good health. However, when the internal state is not in alignment with the aforementioned criteria, the individual falls ill.

Illness arises in the body only when the underlying causes of that illness exist. When the body is not in a state of ease, it is considered diseased. The initial stage of the disease is characterized by experiencing one or more of the Acute Diseases, such as cold, cough, phlegm vomiting, loose motions, fever, boils, body pains, etc. These acute diseases serve the purpose of internal cleansing of the body, which is beneficial to our health. During an acute disease, a person may feel weak externally and uncomfortable internally. It’s important to note that the duration of an acute disease is limited, lasting only a few days (usually two or three days). Once the body has rid itself of foreign matter, the person will regain their health and feel energized.

The occurrence of acute diseases is not limited to adults, as even small children, birds, and animals can develop them. These diseases were common even 70-80 years ago and remain latent in the body until the vital power finds an opportunity to eliminate toxins from the body, making the disease evident. However, if drugs and medicines are used to suppress the disease in its patent form, it goes back to the latent stage and can progress to become chronic or even destructive if repeatedly suppressed. This raises an interesting question: in the past, chronic diseases could be treated using natural methods such as herbs, and destructive diseases were unheard of. It is concerning that even children are now affected by these destructive diseases.
