The teacher explained to me that as the light comes in contact with a person's aura, it takes on the characteristics of that person. What I had observed were the reactions of the light to my own emanations. It therefore is important never to summon the power of the light, when feeling anger, fear or other negative emotions, since these would instantly reflect back on you. Instead, when calling on the light, one should always be centered and relaxed. A good way of achieving the proper frame of mind is to play or listen to music, since this tends to bring about a harmonious and joyful mood.
Conscious breathing achieves a similar effect.
This may be a difficult concept for you to understand. To that end try instead to place your attention on your heart, not as the muscle that moves your blood but as the center of divine love and wisdom in your body, your point of connection with the All Being. Contrary to what you may think the heart is not the center of emotions. Your solar plexus fills that role. Your heart transcends emotions, it is the altar where the Divine interfaces with the portion of Itself that you are.
