"The doctor should be opaque to his patients and, like a mirror, should show them nothing but what is shown to him"

Sigmund Freud's quote suggests that a physician should be neutral and unbiased when dealing with their patients. They need to not permit their own personal feelings or opinions to affect their judgement. Instead, they should act as a mirror, showing back to the patient only what exists to them. This implies that the medical professional must remain neutral and not pass judgement on the client's scenario. They ought to also be respectful of the client's personal privacy and not share any information with others without the client's consent. This quote stresses the value of a doctor being professional and unbiased when handling their patients, so that they can offer the very best possible care.
