The phrase "didst volition" is a somewhat archaic way of saying "made a choice." It implies a deliberate and intentional decision, rather than a random selection or an action taken without thought. Some synonyms for "didst volition" might include "chose," "decided," "selected," "opted," "elected," or "picked." Each of these words carries slightly different connotations - for example, "chose" might suggest weighing options carefully, while "opted" might imply a preference or desire. However, all of these words convey the sense of a conscious decision made with purpose and intent.
