A small extract from Dorn's 'Philosophia speculativa'

This castle of inner truth will destroy many people; it is a cheap thing,
mostly despised and even hated. But one should not hate it, but rather love
it; it is the greatest treasure, it is loving to everybody and hostile to everybody.
You can find it everywhere and practically nobody has ever found it. Change
yourself, the heavenly wisdom says, from dead philosophical stones into living philosophical stones, because I am the true medicine and I change
everything which cannot exist into something eternal. Why are you possessed
by madness? Through yourself but not from you, is everything which you need
and which you wrongly seek outside.

There shines in us, though dimly in darkness, the life and the light of man,
a light which does not come from us, which however is in us, and we must
therefore find it within us. It belongs to Him who has put it into us; we can
find it in Him, in His light. Therefore the truth is not to be looked for in us,
but in the image of God which dwells within us, that is the one thing which
has no second other thing. It is the Being and is in itself the whole of existence.
