"The essential thing about birds is that they, having as their domain the air element, mediate between the earthly realm and the heaven world."
"The alchemist in observing the flight of birds, recognized in them a picture of the human soul undergoing spiritual development. The soul, aspiring upwards, flying free of the restraints of the earth bound body seeking the heavenly light, only to have to return to the earthly consciousness again after the meditation, the alchemist symbolized by the bird."
