Throughout time, many of the prophets were able to heal people of their illnesses. But what was the purpose in the ability to heal the sick? Was this a way of telling people that they represented God? Or did these prophets understand the causes of these illnesses?
If we are to understand the source of our illness, or disease, will we be able to cure our own inflictions? Do all people have the capability to heal? In the Tip of the Writing Brush is the following:
From now on, I shall save you from any pains, sufferings, or tumors by the Sazuke (prayer of healing). 6-106
No matter how serious your illness will become, I shall save you by the Sazuke (prayer of healing). 6-108
However serious an illness will become, never say that it will not be cured. 12-52
Understanding Causality is important in the removal of an illness. Our prayer (sazuke and joyous service) begins this process.
