It is only natural that sometimes we fall sick. But we must see that sickness as a sickness that originally exists in life, based on the principle of the Mystic Law. In other words, there is no reason to allow yourself to be controlled by illness, for it to fill your life with suffering and distress. From the standpoint of eternal life through the three existences, your fundamentally happy self is incontrovertibly established.
