like the pentacles of solomon and other “charged” sigils of history, common to the collective unconscious and holding a particular power of their own, if other people see them once you have started using that technology, you run the risk of their subconscious actually interfering with the energetic trajectory you have established.
it’s like if you set something up that requires precision (for example, personal settings on a guitar amplifier, a computer system, laboratory equipment etc), and don’t warn others not to touch your stuff. you can imagine that, even without hostile intentions, their influence will send your stuff out of whack. with magical technology and sigils etc, once you have directed energy toward a task which is represented by, or manifested through a sigil or other picture, it should not be seen by others at least until the objective is accomplished.
this is because the energy pattern you released is subject to external influences. to this end, psychological retraction is necessary to not derail the operation through excessive worry about the outcome, and if others get “close enough” to said energy patterns via exposure to the sigils used, their subconscious minds will add their own influence to the mix, and send your efforts off course. in an extreme example, a death working or other curse could redirect itself to whoever sees the sigil(s), as magic takes the path of least resistance to manifestation. worse still if they are curious about it, or recognise the pictograms as being “something to do with magic”, as they will then form an active subconscious association with them, and pull your carefully projected energy current into their subjective universe, changing the original and desired outcome.
this is the same reasoning behind “to know, to dare, to will, and to keep silent”. if you tell people about your rituals before they’ve manifested, then their simply knowing about the currents you’ve put into motion could easily alter the course of events, and a critical “coincidence” or happenstance could fail to come about, rendering the operation fruitless.
