Quote of the Day

“We must again repeat that our substance is not collected from many sources; but, as Basilius says, it is one universal thing, and is found in, and obtained from one thing, being the spirit of mercury, the soul of sulphur, and a spiritual salt, united under one heaven and dwelling in one body.”
