Around every person there is a field of emotional energy. Some people always look radiant, and everything in their life flourishes and grows. They have a positive energy field around them. Some people, on the other hand, always have a morose or tense air about them, and everything in their life seems to fade and die. They have a negative energy field around them. A positive field is created by positive emotions and a negative field draws sustenance from negative emotions.
Energy causes all beings to act in this world. The higher the level of energy, the greater would be their accomplishments. When we are tired, our energy levels plummets and we do not feel like doing anything. When the field around is negative with hurt, anger, possessiveness, greed, jealousy, fear and abhorrence, we are less able to act with speed and efficiency. These emotions suck the energy and life force out of us.
