ascesis

The Neo Platonic philosophy, it will now be seen, is monism, and the completion, consequently, of ancient philosophy, so far as it would reduce the totality of being to a single ultimate ground. As able, however, to find its highest principle, from which all the rest are derived, not through self-consciousness and natural rational explanation, but only through ecstasy, mystic annihilation of self, ascesis, theurgy, it is a desperate overleaping of all—and, consequently, the self-destruction of ancient—philosophy.

And this we do find in the Basilican, the Byzantine, and the Romanesque architectures, each more perfect than another, and each lacking in an ever diminishing degree much of the perfect holiness of the Saint of "the most high,"—they came and passed away like different periods in the askesis of a holy soul aiming after the perfection of the spiritual life, and truly therefore they are Christian.
