A typical subliminal is designed to affect the person who listens to it. An exo-subliminal is designed to affect someone or something other than the person who listens to it. "Exo" means "outer" or "away from". This would mean that subliminals we now consider "normal" are actually endo-subliminals ("endo" means "inner" or "within", and in this case refers to affecting the self).

There are three major classes of subliminal in this direction: endo-subliminals, exo-subliminals and hybrids that mix these two.

You might wonder, what good is an exo-subliminal? Well, if manifestation subliminals work (and they do), then we can use our subconscious minds to affect the world around us through exo-subliminals. This makes perfect sense. It's very much like passive guided visualization, done on a completely subconscious level, only there is no need for the visualization part; but the results are the same or better. You make a change in the world and achieve the goal you want to achieve.

An exo-subliminal allows you to use a subliminal to make a change in the world outside yourself. It allows you to put your subconscious mind to work on a target object, situation, possibility or person other than yourself. For instance, let's say you want to cause a cure for all cancer to be discovered. By doing creative visualization, you could put energy toward making this happen. There are other ways too. But with an exo-subliminal, the process is literally effortless and automatic; you simply listen to the program, and your subconscious does the rest, without you having to think about it or try.

The beautiful thing about an exo-subliminal is that because the target is not you, a potentially unlimited number of people can use the same program and add their focus, effort and energy to the mix. According to basic metaphysical energy theory, when multiple people work together on a goal using energy (creative visualization, magick, prayer, whatever), the ideal result is not a linear progression (1 person generates 1 unit of energy, 2 people generate 2 units of energy, 3 people generate 3 units, 4 people generate 4 units) but a geometric progression (1 person = 1 unit, 2 people = 2 units, 3 people = 4 units, 4 people = 8 units).

This is why practitioners of magick, people who use prayer to generate change, and creative visualizers often work in groups: the more people who are focused on the same goal, the more powerful the effect and the more likely the success. The problem arises in managing to get everyone focused properly. The practical upper limit is around 12 people, which is why most groups are about 12 people or less. Beyond that, focus and control are lost and the effects are usually diffused instead of strengthened.

But, with an exo-subliminal, an unlimited number of people can now focus their minds on the exact same goal, in the exact same way for as long as desired. So let's say our goal is causing a cure for cancer to be discovered. 12 people using coherent creative visualization (and producing the equivalent energy and results of 2,048 people on their own doing the same thing) might have to repeat the effort a lot to equal the results and energy of a hundred people using an exo-subliminal for the same purpose for a few months, as that hundred people would be generating a continuous effort equivalent to 100^2 (100,000) people 24/7 for the same period of time.
