No destiny attacks us from outside. But, within him, man bears his fate and there comes a moment when he knows himself vulnerable; and then, as in a vertigo, blunder upon blunder lures him.
The quote reflects the idea that destiny is not an external force but rather something inherent within each person. It suggests that individuals carry their own fate and that self-awareness can often reveal vulnerabilities. This realization can lead to a sense of instability, where one might feel overwhelmed by life's challenges.
