“Nothing in our everyday experience gives us any reason for supposing that water is made up of hydrogen and oxygen; and yet when we subject water to to certain rather drastic treatments, the nature of its constituent elements becomes manifest. Similarly, nothing in our everyday experience gives us much reason for supposing that the mind of the average sensual man has, as one of its constituents, something resembling, or identical with, the Reality substantial to the manifold world; and yet, when that mind is subjected to certain rather drastic treatments, the divine element, of which it is in part at least composed, becomes manifest, not only to the mind itself, but also, by its reflection in external behaviour, to other minds.”
