Dis-ease begins in thought.

The mental thought patterns that cause the most dis-ease in the body are CRITICISM, ANGER, RESENTMENT and GUILT. For instance, criticism indulged in long enough will often lead to dis-eases such as arthritis. Anger turns into things that boil and burn and infect the body. Resentment long held festers and eats away at the self and ultimately can lead to tumors and cancer. Guilt always seeks punishment and leads to pain.
