Paranoia is a word that has entered the popular vocabulary. Literally, (although, of course, not technically) it means to be out of your mind. To be paranoid is to have lost your way, like Dante wandering in a land that is far from home. There is another word, which has not yet entered popular speech, for the turning of the mind to the lost home: metanoia.
The path of metanoia is a way of glory which leads us home. . . . Metanoia (to turn the mind, to be in your right mind), . . . means the restoration of mind, the coming together of the shattered fragments of the self. It means a turning to God as the source and power of life.
