Yes, me, again :) In love with this line of inquiry and have so much to share I hardly know where to begin... The logical answer is the miracle's modesty or how it conceals itself ;) Which is to say, yes, some mystics are epileptics, but not all epileptics are mystics. Likewise, there is a fine line between madness and genius or Vision and only the very wise, or initiated, may comment upon where one begins and another ends...
To quote Joseph Campbell on this complicated subject — 'The psychotic drowns in the same waters in which the mystic swims with delight.'
In Egypt, where I come from, eccentrics, 'street prophets' and the seemingly mad, are regarded with some deference since they are viewed as possessing minds that are divinely licked. Who's to say, as you say...
