It commonly announces the advent of an entity that is barely able to manifest, and need not necessarily be a herald of evil at all.
It may simply be a knock on the door of the physical world to attract the attention of the inhabitants to the presence of one who stands without and would speak with them.
If, however, it occurs in the presence of other symptoms of an astral attack, it would give strong evidence in confirmation of the diagnosis.
Inexplicable outbreaks of fire are also sometimes seen in this connection.
These indicate that elemental forces, not human, are at work.
Poltergeist phenomena also occur, in which objects are flung about, bells rung and other noisy manifestations take place.
Of course there may be multiplicity of phenomena, more than one type appearing in the same case.
Needless to say, the possibility of some natural, material explanation must never be ignored, even in cases where the supernatural element appears most obvious.
It should always be diligently sought in every possible direction before any supernormal hypothesis is considered worthy of attention.
But on the other hand, we should not be so wedded to materialistic theories that we refuse to take a psychic theory as a working hypothesis if it shows any possibility of being fruitful.
After all, the proof of the pudding is in the eating, and if, working on an occult hypothesis, we are able to clear up a case which has resisted all other methods of handling, we have pretty good evidence in support of our contention.
We must also bear in mind that the element of deliberate fraud may enter into the most unexpected places.
I have seen a drug addict successfully pass himself off for a considerable length of time as the victim of an occult attack.
A recent writer in the British Medical Journal declared that whenever he came across a case of bell-ringing, knocks, the dripping of water and oil from ceilings, and other untoward happenings, he always looked for the hysterical maidservant.
Occultists would be very well advised to do likewise before they begin to worry about the Devil.
But on the other hand, the wise man, whether occultist or scientist, will not insist upon the hysterical maidservant unless he can catch her red-handed, as he surely will do sooner or later if she is the guilty party.
Forged bank-notes would never gain currency unless there were such a thing as genuine bank-notes.
It would never occur to anyone to produce fraudulent psychic phenomena unless there had been some genuine psychic phenomena to act as a pattern for the forgery.
The acceptance of an explanation should rest upon the weight of evidence in its favour, not upon one’s dislike of its alternatives.
I plead that the possibility of a non- material explanation should be investigated in cases where the materialistic hypothesis does not yield results.
Not in diseases of the brain and nervous system, nor of the ductless glands, nor in repression of the natural instincts, shall we find the explanation in all cases wherein the mind is afflicted.
There is more to man than mind and body.
We shall never find the clue to the riddle of life until we realise that man is a spiritual being and that mind and body are the garments of his manifestation.
The doctrine and practice of one person deliberately inflicting harm on another through trained will, mind-power, or occult technique alone, without physical contact — producing exhaustion, illness, breakdown, or death in the victim; recognised cross-culturally as witchcraft, hexing, or the evil eye, and treated in Western esotericism as a genuine occult hazard requiring diagnosis and defence rather than dismissed as superstition. Distinct from magical_will (the general doctrine that trained volition has causal power, of which this is one malevolent application) and from spirit_conjuration (which subordinates an already-existing summoned spirit, rather than directing the operator's own power at a person).
The passage is explicitly titled 'Signs Of Psychic Attack' and discusses diagnosing astral attacks, distinguishing them from natural causes or fraud.
Division of the human being into three principles: spirit (pneuma), soul (psyche), and body/matter (hyle or soma).
The text asserts that 'There is more to man than mind and body' and that man is a spiritual being with mind and body as garments, implying a threefold constitution.
