Whom I call must follow

"Every man that hath seen me forgetteth me never,
and I appear oftentimes in the coals of the fire,
and upon the smooth white skin of woman,
and in the constancy of the waterfall,
and in the emptiness of deserts and marshes,
and upon great cliffs that look seaward;
and in many strange places, where men seek me not.
And many thousand times he beholdeth me not.
And at last I smite myself into him as a vision smiteth into a stone,
and whom I call must follow."
The Vision and the Voice, 2nd Aethyr, ARN
