In James Clavell's "Shogun," the quote "Like dew I was born. Like dew I vanish... and all that I have ever done is but a dream within a dream" reflects on the transient nature of existence. It suggests that life is fleeting, much like dew that appears in the morning only to evaporate with the sunlight. This imagery conveys a sense of impermanence, urging readers to contemplate the ephemeral quality of their experiences and achievements.

The metaphor of life being a dream within a dream highlights the complexity of reality and perception. It implies that what we perceive as solid and lasting may be merely an illusion. Clavell's work encourages deep reflection on the meaning of life and the legacy we leave behind, reminding us that all our endeavors might ultimately fade away, much like the morning dew.
