…consider a final parable, which comes from Aleister Crowley’s Magick in Theory and Practice and is said by him to contain the whole secret of practical occultism:
Two passengers are sharing a railway carriage. One notices that the other has a box with holes in it, of the sort used to transport animals, and asks what animal his companion is carrying. “A mongoose,” says the other. The first passenger naturally asks why this eccentric chap want[s] to transport a mongoose around England.
“It’s because of my brother,” says the second man. “You see, he drinks perhaps more than is good for him, and sometimes he sees snakes. The mongoose is [to] kill the snakes.”
“But those are bleeding imaginary snakes,” says the first man.
“That’s as may be,” says the other placidly. “But this is an imaginary mongoose.”
