Is the use of techniques to remove fears and negative beliefs from the subconscious mind permissible in Islam?

The mind operates in a single way with two components: one conscious and the other unconscious. In our time, people have delved into techniques for controlling the mind and exploiting its capabilities. However, many of these lack a scientific basis and rely on ancient Eastern cultures that have no origin in Islamic or experimental sciences. Examples include: subliminal perception, bio-energy sciences, and the law of attraction.
