Jowett: habit of the soul

And what is purification but the separation of the soul from the body, as I was saying before ; the habit of the soul gathering and collecting herself into herself, out of all the courses of the body ; the dwelling in her own place alone, as in another life, so also in this, as far as she can ; the release of the soul from the chains of the body ? PHAEDO  

Ath. The affection both of the Bacchantes and of the children is an emotion of fear, which springs out of an evil habit of the soul. And when some one applies external agitation to affections of this sort, the motion coming from without gets the better of the terrible and violent internal one, and produces a peace and calm in the soul, and quiets the restless palpitation of the heart, which is a thing much to be desired, sending the children to sleep, and making the Bacchantes, although they remain awake, to dance to the pipe with the help of the Gods to whom they offer acceptable sacrifices, and producing in them a sound mind, which takes the place of their frenzy. And, to express what I mean in a word, there is a good deal to be said in favour of this treatment. LAWS BOOK VII
