The Enneads of Plotinus

"That great soul must stand pictured before another soul, one not mean, a soul that has become worthy to look, emancipate from the lure, from all that binds its fellows in bewitchment, holding itself in quietude. Let not merely the enveloping body be at peace, body's turmoil stilled, but all that lies around, earth at peace, and sea at peace, and air and the very heavens. Into that heaven, all at rest, let the great soul be conceived to roll inward at every point, penetrating, permeating, from all sides pouring in its light. As the rays of the sun throwing their brilliance upon a louring cloud make it gleam all gold."
Plotinus: The Enneads, Fifth Ennead, First Tractate, No. 2, Paragraph 3, (Mystery Religions, Greek, Words of Plotinus)
