Sri Chinmoy: Usually it is built consciously. Some seekers feel that when they are around unaspiring people they need protection to maintain their high consciousness. They are afraid they will be attacked by unaspiring people who will enter into them like arrows and destroy their aspiration, so they consciously build a wall around themselves. Sometimes ordinary people who are not aspiring have a tremendous insecurity. They are afraid that others will take away whatever little wealth they have. And spiritual Masters may build this wall to protect themselves from the attacks of the consciousness of the world around them. Some people come into the presence of a spiritual Master and feel that once they have come that is more than enough. They do not want to accept anything. The moment the Master wants to give them Peace or Light, they attack him inwardly. Or people come to a Master without knowing what they want, and when Peace is offered, they feel that it is something strange. When Light is offered or Bliss is offered, they feel it is something strange. They feel that they are not being given what they want, so they come and attack. Or they come and bother the Master, saying, “Give me, give me, give me!” Then when it is given they don’t take it. At that time the Master creates an aura for self-protection.
Each individual has a special aura, of which he is not conscious. That aura, the most important aura, goes around the person from head to foot. It consciously protects the person. When you meditate you may see that there is an aura constantly revolving around you. Other auras you may also see, behind pictures of the Buddha or Christ, for example, but usually these do not revolve or move. But this aura that we all have is constantly moving around us. But we have to know that this aura is not all-powerful. It is only a strong protection on the physical, vital and mental level. It does not protect the whole being. This aura becomes all-powerful only through our prayer and meditation. Each day when we pray and meditate this aura is strengthened. It moves faster, very, very fast. And when the movement becomes extremely fast, the aura acquires tremendous strength, enough to protect the entire being.
