Mystical states cannot be sustained for long. Except in rare instances, half an hour, or at most an hour or two, seems to be the limit beyond which they fade into the light of common day. Often, when faded, their quality can but imperfectly be reproduced in memory; but when they recur it is recognized; and from one recurrence to another it is susceptible of continuous development in what is felt as inner richness and importance.
