Okay, first of all, auras reflect who we are. Second, I don't know what chakras really are, but of all I know, they're energies. So they ARE real.
Mr_x is right chakras flow through your body and you can learn how to control it, to balance your energy. I use to study spiritual satanism, it had a lot of chakra talk. They also used the chakra to summon/speak to demons. And mood rings are fake
Auras are not like mood rings. They do NOT go by your mood. Everyone has an aura and every aura has a color. But please don't mix it up by saying they go by mood.
