(i heave already posted a comment about this subject but reread it and found it sloppy so i am redoing it to explain better.)
1. before you can learn to see auras, you must work on your periphel vision. there is some exercises to help with this if you ever look it up on google.
2.periphel vision is your side vision and more sensitive because they are not as much exposed to light.
3. kids vision is better then adults because they are not as damaged yet.
4.ANYONE CAN SEE AURAS.
before you start seeing auras you must know what they are. EVERY living and non-living thing has an aura. an aura is its energy. although human auras are stronger then objects you can still see them.
there is many layers of an aura. like the first one is very easy to see, it is usually a pale colored outline of the object or human. then the nxt layers are colorful.
the next thing you need to develop auric vision is a third eye(as you would like to call it.) it helps alot.
HOW TO SEE THEM:
if this is your first time doing this i would use a bright object and a netural color backround. then look past and to the side a little bit and keep your eye on one spot. this is the trickey part: you must know how to relax n focus at the same time.
if you know how to keep your eyes on the spot and do just that. you will see the first layer then a color. dont look directly at it or it will vanish. once you have done that keep practicing.
PRACTICE IS THE KEY. you can practice anywhere! (just dont stare at strangers!)
good luck n blessed be!
i almost forgot... when you look at people`s auras it could be just the clothing auras. clothing is known to do that so hopefully the person is not wearing bright colors....
