Always the same duration of sessions – helps to avoid any pretexts on the part of the patient to limit him from any positive or negative premeditation: prolongation, reduction or cancellation of sessions.

When we read the chapters on countertransference and on transference, we will definitely find a reference to the analyst's neutrality.
So what is neutrality? What is the difference between neutrality, neutral, neutrality? What are the characteristics?
