Question: Can meditation be used to increase a person's IQ?

Sri Chinmoy: Certainly. Anything that is progressive, anything that is illumining, anything that is fulfilling is the result of conscious or unconscious meditation. If the meditation is conscious, then the progress is noticeable sooner than at once. If the meditation is unconscious, then the progress cannot be quick and it may not be noted outwardly.
