Learn how to see Auras
Your aura changes according to what is going on around you. If one minute you're happy and energetic and the next you hear bad news, an aura can change in a spilt second. Even thoughts can change our energy. Think about something sad and you'll feel tired or lose energy. Now change your thoughts to something more positive and happy and you'll feel the changes immediately within. A trained eye can see the aura changing instantly! It can be of a single colour or many different colours.
You can use your intuition when reading someone's aura. Many people have been seeing colours around others for years, every since they were small children. This is not unusual. If you are one of these folks who already sees colour, you are seeing auras! If you do not naturally see these auras then don’t worry, you can learn to, just like any other skill it just takes a little practice.
