Progressive muscular relaxation is a technique taught to reach a deep state of relaxation First you tense a muscle and hold it for a few seconds then release that tension to bring a deep sense of relaxation. Controlled breathing exercises also promote relaxation. In visualisation a therapist guides you to find pictures in your mind that are peaceful and healing to you.
