The path by which some come to see the Light, to find the Rock of Ages, is the simple path of honest self-knowledge, self-renunciation, self-restraint, in which every upward step towards right exposes some fresh depth of inward sinfulness, till the once proud man, crushed down by the sense of his own infinite meanness, becomes a little child once more, and casts himself simply on the generosity of Him who made him. And then there may come to him the vision, dim, perhaps, and fitting ill into clumsy words, but clearer, surer, nearer to him than the ground on which he treads, or than the foot which treads it -- the vision of an Everlasting Spiritual Substance, most Human and yet most Divine, who can endure; and who, standing beneath all things, can make their spiritual substance endure likewise, though all worlds and eons, birth and growth and death, matter and space and time, should melt indeed --

And like the baseless fabric of a vision,
Leave not a rack behind.
