Here is the joke we tell about ourselves:
Q: How many chiropractors does it take to change a light-bulb?
A: Only one, but it will take thirty visits before it works!
Point being, we are working with a natural system, not overpowering it. So each visit releases stuck tensions, but the body will only accept a certain amount of change. Successive visits allow more change until all the light-bulbs work. The goal isn’t to return to the point the patient experienced before pain set in; rather, to bring the person to deeper place of health than wasn’t on the precipice of collapse. So while you may have thought you were happy before you experienced pain in your body, the causes leading up to it were already in place.
Leaving with a quote from the Buddhist scholar, Nichiren Daishonin:
“Those who spend too long in the toilet, get used to the smell.”
