When imagination became a line of defense
In Dion Fortune’s occult framework, an astral shield was more than a comforting image. “Astral” referred to a nonphysical realm that occultists believed could affect ordinary life, while visualization meant deliberately forming a vivid mental picture and holding it in place. The imagined barrier was meant to protect the person from influence coming from that realm.
That makes the practice easier to understand as a kind of ritualized boundary-setting. Fortune described threats as forces that could cross the gap between the invisible and the everyday; picturing a protective aura gave her a specific action to take against them. The shield was not a physical object, but within her account, focused imagination was itself a tool.
A household caught in the explanation
Fortune connected the supposed attacks not only to sensations she experienced, such as scratching, but also to her cats’ illnesses. That connection shows how broad the perceived danger had become: events affecting both a person and animals in her home could be interpreted as parts of one hostile influence.
Her story is best read as an account of what she believed and how she responded, not as evidence that psychic forces caused the harm. Its revealing detail is the practical role the belief played: aura visualization turned an invisible threat into something she could actively resist, even when she could not point to a visible attacker.
