Some definitions of counseling overlap with psychotherapy (particularly in non-directive client-centered approaches), or counseling may refer to guidance for everyday problems in specific areas, typically for shorter durations with a less medical or 'professional' focus. Somatotherapy refers to the use of physical changes as injuries and illnesses, and sociotherapy to the use of a person's social environment to effect therapeutic change. Psychotherapy may address spirituality as a significant part of someone's mental / psychological life, and some forms are derived from spiritual philosophies, but practices based on treating the spiritual as a separate dimension are not necessarily considered as traditional or 'legitimate' forms of psychotherapy.
