I saw green arua aroudn my shioulder, and white aura around head. Is this a good sign? does this mean a person become clairvoyant?

A very interesting question this one but I don't see it as becoming clairvoyant, to be able to explain it any better one of the other members here should have an answer for you.

Color is something we all develop, symbolically, with our own spirit guidance.  Green generally means growth - look around at nature - green is the color of the growth of all the living plants.  A strong green in the aura can mean opening to the growth that is all around.  

Like all things there can be an opposite meaning as well.  Keep in mind, leaning to the positive in all things, keeps life positive.  Green is considered the color of jealousies.  Beware of your own or others around you.

White is the highest color of spirit because it contains all the colors.  Around the head is the connection point (crown) to spirit influence from the highest power (God) to the spirit guidance.  All things will be on a spiritual basis as they open to your awareness.

When I first started seeing auras it was green around my hands and shoulders and white around my head but after some time I started seeing like a blue-green around my head.

Hi beebee,

I would take the green to be an area of healing, green for me symbolises the growth and repair stage. It is wonderful to see any aura so if I was you I would be quite happy and carry on learning and exploring about them and using them.
