Paracelsus said this quote

Medicine rests upon four pillars—philosophy, astronomy, alchemy, and ethics. The first pillar is the philosophical knowledge of earth and water; the second, astronomy, supplies its full understanding of that which is of fiery and airy nature; the third is an adequate explanation of the properties of all the four elements—that is to say, of the whole cosmos—and an introduction into the art of their transformations; and finally, the fourth shows the physician those virtues which must stay with him up until his death, and it should support and complete the three other pillars.

~ Paracelsus

There is an earthly sun, which is the cause of all heat, and all who are able to see may see the sun; and those who are blind and cannot see him may feel his heat. There is an Eternal Sun, which is the source of all wisdom, and those whose spiritual senses have awakened to life will see that sun and be conscious of His existence; but those who have not attained spiritual consciousness may yet feel His power by an inner faculty which is called Intuition.

~ Paracelsus

Death is the midwife of very great things.... It brings about the birth and rebirth of forms a thousand times improved. This is the highest mystery of God.

~ Paracelsus

Be not another, if you can be yourself.
