A bad habit in a previous life is a cause of disease in the next one, whereas a good habit results in health. In this way are people led to infectious diseases through their own disposition.
We all know of one who can travel the world to areas ridden with epidemics or contagious diseases, mingling with many individuals, without suffering any ill. But we also know of another who will contract an infection by merely walking down the street.
It is one’s disposition which determines whether or not one is prone to infection. The initiates know for a fact that a predisposition to infectious diseases originates from the selfish habits of thinking in a previous life. They know how a pronounced desire to possess and gather riches for oneself leads to infectious diseases.
