In mythology, Neptune is often associated with the vastness and power of the ocean, which can serve as a metaphor for the depth and power of the human soul. The ocean is a symbol of the unconscious, the unknown, and the mysterious depths of the human psyche. Similarly, the soul is often seen as a deep and mysterious aspect of the human experience, containing vast potential and untold depths of wisdom and insight. The artwork that portrays Neptune can remind us of the vast depths of our potential, inviting us to explore the mysteries of our own soul and tap into the power that lies within.
