" It is not right to make an incantation of ‘Who am I?’. Put the question only once and then concentrate on finding the source of the ego and preventing the occurrence of thoughts.” ‘Finding the source of the ego,’ implies concentration on the spiritual centre in the body, the Heart on the right side, as explained by the Maharshi. And, so concentrating, ‘to prevent the occurrence of thought’. “Suggestive replies to the enquiry, such as ‘I am Siva’, are not to be given to the mind during meditation. The true answer will come of itself. No answer the ego can give can be right. These affirmations of auto suggestions may be of help to those who follow other methods but not in this method of enquiry. If you keep on asking the reply will come.” The reply comes as a current of awareness in the Heart, fitful at first and only achieved by intense effort, but gradually increasing in power and constancy, becoming more spontaneous, acting as a check on thoughts and actions, undermining the ego, until finally the ego disappears and the certitude of pure Consciousness remains.
