Tadpoles
The frog is amphibious and can dwell in both the realms of the conscious and the unconscious, as represented by land and water. This intermediary state of tadpole signifies the natural order of things to begin in the inner realms before venturing out into the air. There is a connection to the tadpole and the notion of ideas that must swim around in the nurturing ponds of your mind before they are ready to spring forth into action.
