And from hence it is, That the Souls of the dead are not easily to be raised up, except is be the Souls of them whom we know to be evil, or to have perished by a violent death, and whose bodies do want a right and due burial.
Now although we have spoken concerning such places of this kinde, is will not be safe or commodious to go unto them; but it behoveth us to take to what place soever is to be chosen, some principal part of the body that is relict, and therewith to make a perfume in due maner, and to perform other competent Rites.
It is also to be known, That because the Souls are certain spiritual lights, therefore artificial lights, especially if they be framed out of certain competent things, compounded according to a true rule, with congruent inscriptions of Names and Seals, do very much avail to the raising up of departed Souls.
Moreover, these things which now are spoken of, are not alwaies sufficient to raise up Souls, because of an extranatural portion of understanding and reason, which is above, and known onely to the Heaven and Destinies, and their power.
We ought therefore to allure the said Souls, by supernatural and coelestial powers duely administred, even by those things which do move the very harmony of the Soul, aswel imaginative, as rational and intellectual; as are Voices, Songs, Sound, Inchantments: and Religious things; as Prayers, Conjurations, Exorcismes, and other holy Rites, which may very commodiously be administred hereunto.
