Vision

 Ecstasy or vision begins when thought ceases, to our consciousness, to proceed from ourselves. It differs from dreaming, because the subject is awake. It differs from hallucination, because there is no organic disturbance: it is, or claims to be, a temporary enhancement, not a partial disintegration, of the mental faculties. Lastly, it differs from poetical inspiration, because the imagination is passive.
