"I also approve thy Book, and I give thee my true signature on parchment, which thou shalt affix at its end, to make use of at thy need. Further, I place myself at thy disposition, to appear before thee at thy call when, being purified, and holding the dreadful Blasting Rod, thou shalt open the Book, having described the Kabalistic circle and pronounced the word Rofocale. I promise thee to have friendly commerce with those who are fortified by the possession of the said Book, where my true signature stands, provided that they invoke me according to rule, on the first occassion that they require me. I also engage to deliver thee the treasure which thou seekest, on condition that thou keepest the secret for ever inviolable, act cheritable to the poor and dost give me a gold or silver coin on the first day of every month. If thou failest, thou art mine everlastingly." -- LUCIFUGE ROFOCALE
