The Key to Life and Death is everywhere to be found, but if you do not find it in your own house, you will find it nowhere. Yet, it is before everyone’s eyes. No one can live without it. Everyone has used it. The poor usually possess it more than the rich. Children play with it in the streets. The meek and uneducated esteem it highly, but the privileged and learned often throw it away. It is the only thing from which the Philosopher’s Stone can be prepared, and without it, no noble metal can be created.
People who blindly follow socially accepted values, beliefs and behavior are no longer connected to the Mystery of this thing and therefore “throw it away.”
Medieval Alchemists frequently referred to this thing as “the corner stone the builders forgot.” In other words, it is something important that is not an integrated part of our current civilization.
