In "The Fires of Heaven" by Robert Jordan, the character grapples with the complexity of understanding another person, likening it to the challenge of grasping the nature of the sun. This metaphor suggests that some aspects of life and individual experiences are inherently elusive and may never be fully comprehended. The quote highlights the futility in trying to completely understand someone, as just like the sun, they can be both illuminating and distant.

The dialogue emphasizes that, despite our efforts, there are limits to human understanding and connection. The idea suggests that instead of striving for complete understanding, it may be more valuable to recognize and accept the mystery that others embody. Ultimately, this reflection on relationships encourages a deeper appreciation for the uniqueness of individuals and the complexities of human nature.
