epiphany
This term describes a flash of sudden clarity where a complex problem or a deep truth becomes instantly obvious. It carries a sense of intellectual or spiritual liberation, often marking a turning point in a person's understanding or life direction. In a religious context, the word refers specifically to the manifestation of a deity to humanity. While the secular usage is common in storytelling and psychology to describe a character's moment of realization, the capitalized form refers to the Christian feast day celebrating the visit of the Magi.
