"...until you find the true, clear Green Lion, which you will recognize by its great weight. You will see that it is heavy and large. This is the Tincture, transparent gold. You will see marvellous signs of this Green Lion, such as could be bought by no treasures of the Roman Leo. Happy he who has learnt how to find it and use it for a tincture!” - Paracelsus.
