Many have said of Alchemy, that it is for the making of gold and silver. For me such is not the aim, but to consider only what virtue and power may lie in medicines.

The art of healing comes from nature, not from the physician. Therefore the physician must start from nature, with an open mind.

The dose makes the poison.

He who knows nothing loves nothing. He who can do nothing understands nothing. He who understands nothing is worthless. But he who understands also loves, notices, sees. The more knowledge is inherent in a thing, the greater the love.

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 highest degree of a medicine is Love.

But is not He who created it for the sake of the sick body more than the remedy? And is not He who cures the soul, which is more than the body, greater?
