In C.G. Jung's "The Red Book: Liber Novus," the central quote emphasizes the importance of embracing life and thoughts that remain possible. It reflects Jung's belief in the potential for personal growth and the significance of fully engaging with one's experiences. By indicating that one should live the life that is still available, Jung encourages a conscious choice to pursue meaningful existence despite life's challenges.

This idea highlights the value of introspection and self-actualization. It invites readers to reflect on their own lives and consider the thoughts they can cultivate, suggesting that one's mental landscape can greatly influence the quality of their life. Ultimately, it serves as a motivational reminder to seize opportunities for personal development and to remain open to new possibilities.
