Man is a microcosm, or a little world, because he is an extract from all the stars and planets of the whole firmament, from the earth and the elements; and so he is their quintessence.
Thoughts create a new heaven, a new firmament, a new source of energy, from which new arts flow.
A mortal lives not through that breath that flows in and that flows out. The source of his life is another and this causes the breath to flow.
When a man undertakes to create something, he establishes a new heaven, as it were, and from it the work that he desires to create flows into him... For such is the immensity of man that he is greater than heaven and earth.
We do not know it because we are fooling away our time with outward and perishing things, and are asleep in regard to that which is real within ourself.
The physician must give heed to the region in which the patient lives, that is to say, to its type and peculiarities.
Dreams must be heeded and accepted. For a great many of them come true.

For one country is different from another; its earth is different, as are its stones, wines, bread, meat, and everything that grows and thrives in a specific region.
The art of healing comes from nature, not from the physician. Therefore the physician must start from nature, with an open mind.
The dreams which reveal the supernatural are promises and messages that God sends us directly: they are nothing but His angels, His ministering spirits, who usually appear to us when we are in a great predicament.
