In Nabokov's "Ada, or Ardor: A Family Chronicle," the quote reflects a profound sense of surrender and transformation in the face of fate. The character is willing to relinquish their identity and past at the crucial moment when destiny calls. This suggests a deep connection between personal desires and the unavoidable forces of life, highlighting the theme of love and destiny in the narrative.
The idea of surrendering oneself at the first call of destiny implies a readiness to embrace change and the unknown. It speaks to the character's commitment to another person, indicating that love can lead individuals to redefine themselves entirely. The emotional weight of this surrender sets the tone for the complex relationships and existential questions explored throughout the novel.
