I dont know where you get/heard/read that the audios have sigils.
But let me explain in a simple way this:
And ill use an example.
Fax machines.
Is the same aa asking “how a machine can cause another machine far away to receive the information i sent in a paper from the 1st one?”
Energy
Conduits
Transmission
Codification
So the fax machines have a codification just like a smart phone, a codification that allowes the other machine to replicate what is reading when the paper is put in the first machine, the codification could be captured by images that then would have specific codification so when the other machine receives it then can exactly replicate it.
And like that example we have tons.
But how is it sent? Via electrical signals.
That example is more or less to remind you that in this day and time we constantly send / receive information in the distance or using conduits in this case audios
Different things use different ways and mechanisms
But more or less in a wider or smaller scale it reduces to electrical signals, vibrations, energy transmission.
Using that same “vocabulary” an audio is programmed/codified etc with the information to get rid of the hair in the back. In Sapien Medicine’s case his audios/Mandalas are created as Morphic fields, (you can search the forum for that like) :
Deeper Understanding of the Principles of Morphic Fields
So the audio is codified with the command to get rid of the hair, with an energy that would do that.
That energy is imprinted in the sound, the sound is simply the carrier of that energy specifically created to get rid of the hair in the back.
You then play the audio, the sound emits the energy it was made for and your aura which is like having millions of antennas absorbs that energy, and once is absorbed it goes straight to the hair in your back because thats exactly the command the energy was programmed to carry.
So forget about frequencies, this is not it. Not Sapien Medicine, which may be what is confusing for you when you say:
Because its not that, there is not a list of “frequencies” for this or that goal no, its not like the frequency of love or for whatever else, nor this is like Healing codes where you can google “what is the code to lose weight” no.
These are Morphic fields.
Sigils, are just simply another conduit to transmit codified energy to call it some how.
