Air and lasciviousness

Paracelsus says in his book, De Origine Morborum Invisibilium, lib. iii: "(Morbid) Imagination is the cause of Incubi and Succubi and fluidic Larvae.

"The Incubi are male and the Succubi female egos. They are the outgrowths of an intense and lewd imagination (Lasciviousness) of men or women, and after they take form they are carried away. They are formed of the sperm found in the imagination of those who commit the unnatural sin of masturbation in thought and desire."

"Coming as it does from the imagination alone, it is no true sperm, but only a corrupted salt (essence). Only a sperm that enters the organs which Nature provided for its development can grow into a body. If seed is not planted into the proper soil it will rot. If sperm does not come into the proper matrix it will not produce anything good, but something useless. Therefore the Incubi and Succubi grown out of corrupted semen, without the natural order of things, are evil and useless; and Thomas of Aquinas has made an error by mistaking such a useless thing for a complete one."

"This sperm, coming from the imagination, is born in Amor Hereos (Love called eros is a disease touching brain. For it is a great longing with the intense sexual desire and affliction of the thoughts.). This means a kind of love in which a man may imagine a woman, or a woman a man, to perform the connubial act with the image created in the sphere of the mind. From this act results the expulsion of an ethereal fluid, impotent to generate a child, but capable of bringing Larvae (Lust) into existence."

"Such an imagination is the mother of a luxurious unchastity, which, if continued, renders man impotent and woman sterile, because much of the true creative and formative power is lost by the frequent exercise of such a morbid imagination. This is frequently the cause of moles, abortions, miscarriages, and malformations. Such corrupted sperm may be taken away by spirits that wander about at night, and who will carry it to a place where they may hatch it out. There are spirits that will perform an 'act' with it, as may also be done by witches, and, in consequence of that act, many curious monsters of horrible shapes come into existence" (De Orig. Morb. Invis.).

"If such monsters (Egos) are born from a powerful, conscious imagination, consciousness will also be created (trapped) in them. The spirits of night can use all that is born from such sperm according to their pleasure, but they can use nothing of a human character or possessing true spirit."

"Amor hereos is a state of the invisible body, and is caused by an overheated imagination, stimulated to such an extent as to eject sperm, out of which Incubi and Succubi grow.

"In ordinary nocturnal pollutions, the body loses sperm without any effort of the imagination, and the spirits of night can therefore not use it for their purposes." - Paracelsus
