Suggestion refers to the act of influencing or guiding someone's thoughts, beliefs, or behaviours through indirect means. In mental self-help, suggestion is often used as a tool for promoting positive change, such as in hypnotherapy or guided meditation.

The power of suggestion lies in its ability to influence the subconscious mind, which is more susceptible to suggestion than the conscious mind. Suggestions can be delivered through verbal or nonverbal means, such as tone of voice, body language, or visual cues.

In hypnotherapy, suggestion is often used to promote relaxation, reduce anxiety, or overcome limiting beliefs. By guiding the individual into a relaxed and suggestible state, the therapist can deliver positive suggestions to the subconscious mind, which can promote positive change in behaviour or beliefs.

In guided meditation, suggestions are often used to promote mindfulness, focus, or relaxation. By using suggestive language and visual imagery, the individual can be guided into a state of heightened awareness and focus, which can improve mental wellbeing.

It is important to note that while suggestion can be a powerful tool for promoting positive change, it is not a substitute for conscious effort and intention. Personal growth and change still require conscious effort and commitment.
