I think like with most visual fascination inductions, part of what you're playing with is just the incomprehensible beauty of the world. It's easy to get lost in the idea that this specific point of fixation is special. That there's magic contained in watches, crystals, or thumbnails. The "magic" exists in the description, in the perspective, in the voice.
[Outside of an eye, you can see the eyelid, which is controlled by an indistinct number of muscles that human brains are precisely tuned to extract information from. Its position is held in place and can indicate countless emotions and intentions, as well as how tired an individual may be. It's speckled with a set of eyelashes. A kind of biological windshield wipers. They fall off on occasion and are said to grant wishes.]
Anything you look at, you can find an immense body of work studying it, and if not that you can spend just as much time discussing it. Everything is a part of this absurd interconnected fabric of reality. Look closer and you can see wear marks, you can see where it was last touched, you can see how it was created, you can see how it grew. How much thought and energy went into everything?
[Much of the eye is taken up by the sclera. The tunica albuginea oculi. A white layer on the surface of the eye made up of collagen and elastic fiber. An essential structural component, it makes up the shape of the eye and protects its interior. If you touch it, you'll find it slightly wet, with an off-plasticy feeling to it. When blood vessels on its surface burst, you'll see what look like red cracks racing across the surface. Like arcs of lightning, reaching between the iris and the eyelid.]
I think in part, the point of the induction is to give you permission to get lost in it. To lose yourself in this incomprehensible beauty. The hypnotist becomes your guide in a way. Walking you through this glorious slice of everything. Through various tricks to help you maintain your focus, it walks you deeper and deeper in beyond where you could go alone.
[The iris is the diaphragm of the eye. An organ that contracts, dilates, and pulls. It can have a wide variety of colors, ranging from blues and greens to browns and greys. These colors themselves occupy a large range, and are not merely a set of options but a set of points on a spectrum. The iris has a darker ring around its edge called the limbal ring, and at the midpoint lies a ringlike structure called the collarette. In the right lighting around the collarette, you'll see a set of dark chasms called the crypts of Fuchs leading deeper into the eye.]
At the same time, while the hypnotist's role here may be to take the subject on a stroll through the world, I'd generally hold that the "magic" so to speak is not in the beauty of the world, but the words spoken. Nothing can be seen until we look upon it. The frame of analysis is the hypnotist's in this way. And thus it is it who wields the story, and can shape the story in whichever direction it desires.
[At the center of the eye is the pupil. It appears totally black, but is in fact a transparent opening. A hole. Behind it sits a dark mass of tissue called the retina that swallows all light that reaches it. This light is filtered through cells, the information of it deconstructed and reconstructed into a coherent image. The pupil in this way acts as a kind of filter. A threshold or a mouth of sorts.]
Then, I think it's important we understand that the beauty of the world is in this way a tool. Wielded by the hypnotist, who shapes it into a coherent story. A narrative. In which the subject may fall in, or be digested, or absorbed, or consumed. The world always exists, and so much of it can be treated like this. The subject at any time could choose to take a perspective to try to begin to see it. But through this filtering, the hypnotist grants it additional meaning.
I mean, mm. I think all stories pick up additional meaning from their storyteller. Biases, hints of a specific perspective, predilections and preferences. By falling into the story, you can forget this. See it all as natural. Blend your perspective with the authors. I think it's in this place that hypnosis exists. But, I think we can't forget the existence of this bias. I think it's interesting, though.
