The goddess Iris is a link between the earthly and spiritual realms in Greek mythology, playing the role of healer. Sometimes she is depicted as travelling via the rainbow, and sometimes she is the rainbow itself, exploring the relationship between the physical and nonphysical. Iris helps clarify the form of the 7 chakra system, an invisible energetic system in the physical body, one that we can travel via meditation to ensure health and wellbeing in all aspects of life.
