Each layer of your aura is a vibrational energy field linked to one chakra. The outside auric layers are larger and vibrating with higher frequencies. The overall size of your auric field is influenced by your physical, emotional and spiritual health. When your chakras are balanced and you feel healthy, your entire aura can stretch out to few metres in radius, and it is very light in colour. Your auric field can be very small when your chakras are out of alignment.
