Do you know what an aura is? The aura is the light around the body. Every person has an aura. The auras of saints can be seen because their auras are very strong. The ordinary people, it is difficult to see their auras because they are not as strong.
Inside the aura are greyish clouds of negative thoughts and emotions that you have generated for many years. You think and feel everyday, 365 days a year, so you can imagine how many thoughts and emotions have accumulated inside your aura. These thoughts and emotions are clairvoyantly seen as greyish clouds floating in the auras of ordinary people.
When you sit down to meditate. have you not noticed that many thoughts pop in and out of your mind? This is called “inner noise”. Actually, the mind has always been jumping from one thing to another. You were simply not aware of it. The greyish clouds of thoughts and emotions within the aura are a major source of inner noise. Inner noise interferes with the communication between the higher soul and the incarnated soul.
Ramana Maharishi, a great yogi and saint, used a certain technique to get rid of the inner noise. He sat down, and simply looked at the clouds of thoughts and emotions, then starved them to death. Thoughts and emotions are living beings so when you look at them and you do not react, you do not feed them. In this way they gradually lose their energy and just disintegrate. This process takes a long time.
There are times when the higher soul wants to communicate with the incarnated soul. The higher soul keeps on “shouting” at the incarnated soul, but it does not hear. It does not respond. This is not because the incarnated soul is deaf. The inner noise, generated by turbulent energies in the aura and also in the energy centres, makes it difficult for the higher soul to communicate with the incarnated soul.
