Indigo (Third Eye Chakra) relates to self responsibility - being responsible for one's own life, responsible to oneself to follow the soul's path and needs and trusting one's own intuition. (the ability to see things from a 'higher' viewpoint rather than purely for satisfaction of the ego or one's material comfort.).  The indigo energy connects us to our unconscious self, and gives us the experience of being part of the whole universe. Strengthens intuition, imagination, psychic powers, and increases dream activity.
