"What wonderments are observed in our vessels ! How can we not be in Wonderment of them " - Nicolas Flamel
“Thus it is written that whoever wishes to obtain this work through the labour of his hands must first prepare the body, cleanse it in fire, and purge it of all impurity, so that nothing foreign may remain in it. Only then will the spirit enter it and the work will be blessed. But this must be done with great patience, because haste spoils the work.” “And this image shows how the matter appears inside, enclosed within itself, round and unified. In the centre is the true seed, which the philosophers called the little sun. From this all colours come forth and all transformations proceed. One who knows this sign will not err in the work, for nature herself reveals it.” “Hermes says: ‘Blessed is he who knows this vessel, for in it the Mystery of the Masters is hidden.’”
"All things are concealed in all. One of them all is the concealer of the rest - their corporeal vessel, external, visible, and movable. All liquefactions are manifested in that vessel." — Coelum philosophorum by Paracelsus
