Not necessarily.
One cool way to think of an aura is as the energetic ‘Smell’ that surrounds you.
We could say that that ‘smell’ arises naturally from the contents and movements of your bodymind.
Let’s say that you have an indoor garden; a greenhouse. The smell of that garden is going to be a natural consequence of the soil, the water, and the variety of plants, trees, and flowers that are growing in the garden.
So the ultimate foundation of the smell will be the actual contents and processes of the garden. And I think that the ultimate foundation of your aura is the actual contents and processes of your bodymind system.
At the same time, if you always tightly close the doors and windows of your greenhouse garden, then people who are walking past may actually not smell anything at all. In contrast, if you open the doors and windows, and set up circulation fans that blow the air into the surrounding environment, then people may smell your garden from even quite some distance away.
I think that aura scripting probably works on both of those levels.
On the one hand, it cultivates certain particular attitudinal contents and processes within you; say related to sexuality, success, friendliness, and so on.
On the other hand, it also encourages a radiant openness that expands your energy farther out into the interpersonal field.
Both of those levels could be cultivated intentionally by you as well, without a subliminal. If, during your time playing the subliminal, your system ‘learns’ to move and behave more in that style, then it will be maintained to some degree even after you stop playing the subliminal.
Seems like the kind of thing that could be affected by your own choices and actions.
Similarly, a person could run Revelation of Dreams to more quickly and easily develop the habits and skills of lucid dreaming; and then those skills could also continue to be accessed even when the sub is not being played. After all, people do learn to lucid dream without using subliminals. It’s just probably a slower process for most people.
Like heart rate, breath rate, and blood pressure, auric changes probably belong to those systemic processes that tend to occur below the level (or, outside the scope) of conscious awareness. But for all of these processes, consistent application of awareness tends to result in greater control and connection. Learning to influence your own heart rate is not that difficult, if you work on it. I guess auras may be similar.
In both cases though (i.e., heart rates and auras), it’s probably best to just follow healthy habits and let things develop somewhat organically.
