Now and then, for ... not even a few minutes (it's a few seconds), there is a clear perception of the true Identity, which is perfect Harmony, and then all disorders cease to exist - but ... materially they exist! Take a very simple instance: my teeth are all loose in my mouth - it s a FACT - and it's true that logically, such a condition should be very painful: it's not. And I see that it is so because of a Presence - that I understand very well. But it doesn't get cured, far from it! It's incurable. [[In a letter (see Cent. Ed., vol. 26, p. 352-353), Sri Aurobindo told the story of a yogi who could prolong his life at will (and lived for more than 200 years), but who kept the same toothache till the end, without ever being able to cure it. He was Swami Brahmananda, who, one day in the 1900s, told a disciple of his (Sardar Mazumdar), "As for the tooth, I have suffered from it since the days of Bhao Girdi," that is, since 1761. ]] This physical is truly ... a mystery. page 289 , Mother's Agenda , volume 9 , 26th Oct - 1968
