While many of the goals or desires from both practices overlap, there are distinct differences between hypnosis and meditation which should be clarified.
Hypnosis is appropriate if you have a specific goal you wish to achieve. Be it to regress to a point in our life that has caused trauma, or for a specific desire, such as to stop smoking.
Traditional Meditation is less structured, in that clearing the conscious mind allows thoughts or feelings to surface, while trying not to attach to the emotion of them.
