In reality, he explains, there is no such thing as a cure.
Doctors say they have cured a patient when they have removed the symptoms of a particular problem.
But if you are cured of the flu on Monday, no one in the world can guarantee that on Friday you won't get the flu again. And so when Bikram speaks of curing chronic diseases such as arthritis or slipped disc, he is saying that if you faithfully follow his directions, you will be relieved of your symptoms of discomfort. If you don't continue your Yoga faithfully, fully, or as directed, your symptoms will return. Bikram does not wish to tempt readers to laziness or half measures. For instance those poses marked as good for slipped disc are, it is true, specifically good for correcting that condition.
