“Just as outer seeing is suited to the farmer, inner seeing, which is secret seeing, is suited to the physician." -Paracelsus, quoted in "Paracelsian Moments" with an interesting footnote:
Opus Parmirum, I, 9:46 Paracelsus here relates the internal and the external to the three basic principles of the cosmos: sal, sulphur, and mercurius; in Opus Paramirum he treats of their effects in both worlds.
"The inner nature of everything may therefore be known through Magic in general, and through the powers of the inner (or second) sight." -Paracelsus, quoted in Hartmann
"What is required is an act of sympathetic attraction between the inner representative of a particular object in man's own constitution and its external counterpart." -Walter Pagel
Moreover, this true knowledge does not concern the brain, the seat of conscious rational thinking, but rather the whole person.
-Nicholas Goodrick-Clarke, Paracelsus: Essential Readings, p.23
Philip K. Dick: [Exegesis 3:50] Inner space (of Paracelsus) is perhaps the key as to how the immortal man can be transtemporal and transpersonal.
