Renowned esoteric author Manly P. Hall examines the beliefs of Paracelsus and the fabled spirits associated with the four classical elements, as Paracelsus taught. Paracelsus believed that each of the four primary elements known to the ancients (earth, fire, air, and water) consists of a subtle, vaporous principle and a gross corporeal substance. This is fundamental learning for any student of the occult sciences.
