Health, Food and Healing in Yoga

     ... This is not to say that there are no microbes: there are, there are many more microbes than are known now. But it is not because of that you are ill, for they are always there. It happens that they are always there and for days they do nothing to you and then all of a sudden, one day, one of them gets hold of you and makes you ill - why? Simply because the resistance was not as it used to be habitually, because there was some disequilibrium in some part, the functioning was not normal. But if, by an inner power, you can re-establish the equilibrium, then that's the end, there is no more difficulty, the disequilibrium disappears.
       There is no other way of curing people. -p110
