Philippa Perry said this quote

When psychotherapy began, it was about the practitioner listening to a patient and interpreting what the patient said, in order to afford the patient insights about his or her psyche. But now we understand that the main curative part of psychotherapy is the relationship itself. It appears not to be relevant which psychology school the practitioner belongs to. What matters is the quality of the relationship and the practitioner's belief in what he or she is offering.
