What is Mysticism? (IV)

From Practical Mysticism, Chapter 1:

The visionary is a mystic when his vision mediates to him an actuality beyond the reach of the senses. The philosopher is a mystic when he passes beyond thought to the pure apprehension of truth. The active man is a mystic when he knows his actions to be a part of a greater activity. Blake, Plotinus, Joan of Arc, and John of the Cross—there is a link which binds all these together: but if he is to make use of it, the inquirer must find that link for himself. All four exhibit different forms of the working of the contemplative consciousness; a faculty which is proper to all men, though few take the trouble to develop it. Their attention to life has changed its character, sharpened its focus: and as a result they see, some a wider landscape, some a more brilliant, more significant, more detailed world than that which is apparent to the less educated, less observant vision of common sense.
