In the exploration of consciousness, each person's mind operates in its own distinctive manner, much like the individual light patterns of lighthouses across the globe. This analogy emphasizes the diversity of thought and mental states among individuals. Some brains function steadily and predictably, while others display erratic fluctuations. The experiences and intensity of thought can vary significantly from one person to another.

Mitchell highlights this variety by comparing minds to celestial objects, suggesting that some are vibrant and full of life, while others may barely flicker. The reference to quasars represents those minds that exist on the outskirts of typical thought processes, illuminating the vast range of intellectual and emotional experiences. This metaphor underscores the unique signatures of individual minds and the complexity of human consciousness.
