Introduction to be given prior to the exercise:

Our body is surrounded by a coloured envelope known as aura. The colours of the aura undergo continuous changes in accordance with the changes in our attitude and emotional pattern. In fact, there is close relation between the aura and our attitudes and emotions.

We can purify the aura by the purity in our attitudes and emotions, and the latter can be gauged through the former. In the present exercise, we have to use our power of visualisation of a particular colour at a particular psychic centre. Then again, with the mental projection, we have to visualise the same colour as spreading all around us and permeating the whole aura around us. Lastly, we have to make use of the technique of auto-suggestion to bring about the change in our attitude or emotional pattern. Deep concentration and alertness are of course to be maintained throughout the exercise.
