Is using subliminals to lighten eye color permissible or forbidden, especially after already noticing a change in color?

It is not permissible to rely on "subliminal messages" to lighten eye color, because it involves taking a means that Allah has not made a means, and it is a type of shirk (polytheism). The proponents of modern materialistic philosophy have taken the "unconscious mind" as an idol they worship besides Allah, turning to it and asking it for their needs, as if it were the Lord. One must be wary of these modern idolatries widespread under names such as neurolinguistic programming, the law of attraction, and energy healing.
