Irvin D. Yalom Quote
One reason patients are reluctant to work in a therapy group is they fear that things will go too far, that the powerful therapist or the collective group might coerce them to lose control--to say or think or feel things that will be catastrophic. The therapist can make the group feel safer by allowing each patient to set his or her limits and by emphasizing the patient's control over every interaction.
