What is the central idea of poem moon mind?

In "Moon Mind", the central idea is that the mind can be compared to a moon, with its ever-changing phases. Just as the moon goes through different phases, from a full moon to a new moon, the mind also experiences fluctuations in its states. These fluctuations can be reflected through the waxing and waning of the mind's clarity, creativity, and emotional depth. The poem explores the idea that the mind is in constant flux, always evolving and transforming, much like the cyclical nature of the moon.
