Research on the effectiveness of subliminal messages shows that while the popularly imagined ability of subliminals to implant ideas is of very limited effectiveness, if any, there is a certain message - only one - that does have a real effect:

A couple years ago researchers Lloyd Silverman and Joel Weinberger published a paper summarizing numerous experiments, the gist of which was that if you flashed a certain message before and after some other, more conventional training technique (e.g., antismoking therapy), you greatly enhanced the therapy's effectiveness. Now things start to get weird. The most effective message is said to be "Mommy and I are one." This is supposedly because "there are powerful unconscious wishes for a state of oneness with `the good mother of early childhood' … and gratification of these wishes can enhance adaptation," according to Silverman and Weinberger. S&W pointed out the following facts: (1) psychologically neutral messages, such as "people are walking," have no effect; (2) disturbing messages, such as "Destroy Mother," have a negative effect, at least on psychiatric patients; and (3) in areas such as the south where the usual term of affection is "Mama" rather than "Mommy," "Mommy and I are one" has no effect.

Interestingly the "key message", the true hidden desire of the human soul, has nothing to do with "sex" despite what modern western culture would lead one to expect. The real desire is to return to Mother. As the researchers say "the good mother of early childhood". Of course this part rests on the materialist assumption that our motivations are all based on this-world experiences. Looking at the matter more realistically from a spiritual perspective, we would say that the One True Desire is for THE Mother, the eternal, all-good Mother worshiped by all cultures before the artificial religions of patriarchy. We cannot help but note that after millennia of "Father God" propaganda, the message "Daddy and I are one" has no effect. A few millennia of heresy has no effect on the eternal human heart.
