The spiritual meaning of Serpentine is connected to the Kundalini energy.
This is the life force energy that runs through our bodies and is often represented as a snake.
The word Serpentine comes from the Latin word Serpentinus, which means “of or belonging to a snake.”
Serpentine is a stone that aids in the activation of the Kundalini energy. Because it is the life energy that flows through our bodies, the Kundalini energy is sometimes compared to a snake.
 
Serpentine is soothing to the emotional body, allowing you to release your fear of change and hardship so that you are able to look ahead to the future with expectation and excitement. It reminds you of the great span of time that the Earth and Nature have been learning, versus the relatively short time that humanity has inhabited this planet. This perspective can help you feel less self centred and more willing to spend time and energy contributing to the greater good, rather than focusing solely on personal goals.
