Spiritual Meaning:
The embers of a fire will symbolize a spiritual energy that is beginning to die down, to lose its potency.

Psychological / Emotional Perspective:
Embers suggest emotions that have moved beyond a clear expression. Whatever has been our passion is beginning to wane.

Everyday Material Aspects:
As embers are what is left when material has been consumed by fire, we may need to decide whether or not a project or idea needs reviving with new input or allowed to die away quietly.
