In reality illness is only a disequilibrium; if then you are able to establish another equilibrium, this disequilibrium disappears.
An illness is simply, always, in every case, even when the doctors say that there are microbes—in every case, a disequilibrium in the being: a disequilibrium among the various functions, a disequilibrium among the forces.
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.
