Robert Waelder and W.R. Bion share an interest in articulating elemental landmarks within the psychotherapeutic terrain wherein primitive ideation may become transformed into a reclaimed reality orientation. The present paper extends their interest through clinical and literary example. It surfaces an aspect of Bion’s therapeutic calculus, implicit but unstated, in the temporal arrival at multiple and continuously changing “d” structures within the ongoing process of therapy. By recognizing the joint contribution of therapist and patient within these creations in time of arrival at approximations to the depressive position, the authors illustrate the weaving of “white hole” matrices, affording temporary relief from the dread of annihilative anxiety that reclaim the patient’s capacity for non-psychotic self-orientation.
