..when one is in this state of inner harmony and no part of the attention is turned towards the body, the body works perfectly well. It is this… “self-concentration” which upsets everything. And this I have observed many times, many times… In reality one does make oneself ill. It is the narrowness of consciousness, the division. If you let it work, there is… everywhere there is a Consciousness and a Grace that do everything so that all may go well, and it is because of this imbecility that all goes wrong – it is strange! The ego-centric imbecility, it is that which Sri Aurobindo calls “the old man”.
