A rainbow symbolizes the spiritual glory that is available to us through understanding and learning. More esoterically, a rainbow is said to represent the seven steps of awareness necessary for true spirituality. It is the connecting ?bridge? between the physical and the spiritual realms. The raising of consciousness and appreciation of something as ethereal as a rainbow suggests the need for a heightened sense of awareness. When it was realized that white light could be split into its component parts the various colours came to have meaning. For instance, red indicates passion, green fertility, and purple dignity. A rainbow appearing in a dream is the promise of something better to ?ome. The old story of the pot of gold at the end of the rainbow is so firmly entrenched in folklore that this meaning often comes across in dreams.
