Have you noticed. Most mornings after a restful sleep, you feel energized and ready to face the day. You go to work or involved in your normal daily activities with people. When frustrations, anxieties, or challenges present themselves, you are reasonably able to deal with them.
Then by early or mid afternoon you have a more difficult time dealing with the same frustrations, anxieties, and challenges. Everything can seem monumental and you just want to escape for it. You want the day to end and just leave as soon as possible.
Why do you suppose that happens? It happens because by afternoon your aura has decreased and more of the energy around you is penetrating. Most people are not able to take a few minutes over lunch and meditate, do yoga, are have a brief ten minute nap to recharge the aura.
Most people do not realize how sensitive they are to other people's thoughts and feelings. If you have numerous emotional challenges in your life and under a lot of personal pressure, then your aura is inherently weaker. You will have more challenges at work or with family maintaining a strong aura.
