This is an extract from "A note on the philosopher's stone"
"However, if we diligently seek what their ideas all have in common, and if we proceed in accordance with nature, we can identify the following truths, which we can briefly summarize as follows: (1) the effect and ultimate purpose of the Philosopher's Stone is the generation and multiplication of gold. (2) This occurs per speciem similem, that is, each species generates its own. In other words, a lion can only produce another lion and not an elephant, a human produces another human and never a bear, an ox produces an ox and no monkey or other ape, just as barley seed does not produce wheat and wheat seed does not produce beets. (3) In order to reproduce itself, a thing must have its own seed, and each type of seed requires its own type of matrix, or bed, so that it doesn't spoil or produce something that goes against the nature of the thing."
Later on the text says that in order to create gold,you need the essence of gold and it can be extracted by gold itself.
How is this possible if the 2 essences*mercury and sulphur",when combined into a metal become inseparable?
Or did i just get that wrong? Someone here to enlighten me?
