A teacher once said to me, "The face is a reflection of the heart." So if you have a clean heart (good), then your aura will shine, clean and look nice when viewed. All will be comfortable with you.
If your heart is dirty (evil), the aura of your face will look dark. Your days will be unpleasant and everyone seems to want to get away from you. The key to human happiness is the 'heart'. A clean heart will lead you to a life full of luck.
Not the color of the skin that indicates your aura shines. Not a white or black skin that indicates the condition of your heart how.
But a clean heart condition is a noble attitude you can do every day. And everyone is comfortable and happy with you.
