"It is to a practical mysticism that [...you...] are invited: to a training of ... latent faculties, a bracing and brightening of ... languid consciousness, an emancipation from the fetters of appearance, a turning of ... attention to new levels of the world. Thus ... become aware of the universe which the spiritual artist is always trying to disclose to the race. This amount of mystical perception—this 'ordinary contemplation,' as the specialists call it—is possible to all men: without it, they are not wholly conscious, nor wholly alive. It is a natural human activity, no more involving the great powers and sublime experiences of the mystical saints and philosophers than the ordinary enjoyment of music involves the special creative powers of the great musician."
- Evelyn Underhill (1875 - 1941)
