What meditative practices would you recommend?

One of the most effective forms of self improvement in health psychology is visual imagery. One of my professors in university was a health psychologist and used this technique everyday. After ten years she was able to throw away her glasses. She had actually reformed the lenses of her eyes to the point she did not need glasses anymore! Astral Projection is one of the oldest forms of visual imagery and its applications are endless when it comes to finding happiness and love through knowledge of the Self in relationship with the rest of the world.
