The aura is a field of luminous energy that surrounds a living thing. The perception of the aura is often linked to the third eye in Indian spirituality practices. It is also popular with Pagans, Wiccans and New Agers around the world.
Different authors attribute different personality traits to the colors of a person's aura. There For mare many books and websites that claim to teach you to be able to see an aura, but of course many people claim it as a "gift". If you want to get in good with a New Ager or a Pagan, tell him/her that you see his/her aura as orange (confident), emerald green (a healer), or turqoise (another color associated with healers). Watch how quickly they agree with you.
