"So much the rather thou, celestial Light, / Shine inward, and the mind through all her powers / Irradiate; there plant eyes, all mist from thence / Purge and disperse, that I may see and tell / Of things invisible to mortal sight."

"O that our dreamings all, of sleep or wake, / Would all their colours from the sunset take: / From something of material sublime, / Rather than shadow our own soul's day-time / In the dark void of night."

— Keats, John (1795-1821)
