Guided meditations or visualisations help in reaching a state of deep relaxation leading to a state of trance which provides an easy access to the unconscious. They are immensely useful for relaxation, auto hypnotism and giving the mind positive suggestions.
To increase the effectiveness, sit in a quite and comfortable space with the spine erect and use earphones if possible. Please do not use while driving or doing work that requires concentration.
