Paracelsus

"All things are poison, and nothing is without poison; but the dose makes it clear that a thing is not a poison."

"As you talk, so is your heart."

"Belief and work, knowledge and action are one and the same thing."

"Consider that we shouldn’t call our brother a fool, since we don’t know ourselves what we are."

"God has given to all things their course and decided how high and how far they may go, not higher, not lower."

"He who conquers his enemy with meekness, wins fame."

"God, our Father, has given us the life and the art of healing to protect and maintain it."

"He who wants to govern must have insight into the hearts of men and act accordingly."

"If you have been given a talent, exercise it freely and happily like the sun: give everyone from your splendour."

"In us there is the Light of Nature, and that Light is God."

"Practice humility at first with man and only then before God. He who despises man, has also no respect for God."

"All is interrelated. Heaven and earth, air and water. All are but one thing; not four, not two and not three, but one. Where they are not together, there is only an incomplete piece."
