Helena Blavatsky on Devil

“The true doctrine of Buddha says that the demons, when nature produced the sun, moon, and stars, were human beings, but, on account of their sins, they fell from the state of felicity. If they commit greater sins, they suffer greater punishments, and condemned men are reckoned by them among the devils; while, on the contrary, demons who die (elemental spirits) and are born or incarnated as men, and commit no more sin, can arrive at the state of celestial felicity. p. 402”

“"There is a personal God, and there is a personal Devil!" thunders the Christian preacher. "Let him be anathema who dares say nay!" "There is no personal God, except the gray matter in our brain," contemptuously replies the materialist. "And there is no Devil. Let him be considered thrice an idiot who says aye." Meanwhile the occultists and true philosophers heed neither of the two combatants, but keep perseveringly at their work. None of them believe in the absurd, passionate, and fickle God of superstition, but all of them believe in good and evil. p. 31”

“"Shut the door in the face of the daemon," says the Kabala, "and he will keep running away from you, as if you pursued him," which means, that you must not give a hold on you to such spirits of obsession by attracting them into an atmosphere of congenial sin. These daemons seek to introduce themselves into the bodies of the simple-minded and idiots, and remain there until dislodged therefrom by a powerful and pure will. Jesus, Apollonius, and some of the apostles, had the power to cast out devils, by purifying the atmosphere within and without the patient, so as to force the unwelcome tenant to flight. p. 319”
