Remember that you can always make a difference in your world by how grounded and centered you are.  What you radiate outward from your thoughts and emotions--which comprise your aura--is what you attract.  The following is a simple technique which you can practice when coming home from work--or really anytime--to cleanse your aura. 
    Stand on the threshold of any doorway, preferably always the same one.  (This can also work in the shower in the morning.)  Imagine a beautiful white shower of light coming down from Universal Consciousness.  Let it flow all over your body, and into your mind, cleansing it of the tensions of the day.  Imagine the white shower of light touching your arms, legs, neck, back, shoulders, and gently releasing tension and cleansing them.  Imagine the white sjhower of light entering your heart, lungs, kidney, spleen, liver, gently cleansing the organs.  Finally, imagine the white shower of light entering your mind and changing all thoughts within to those of love peace and understanding.  Send those thoughts of love, peace and understanding out into the room and the universe through your heart chakra.
    When you are in balance, you balance your world.  All is at peace and safe within your world.  And so it is.
