Sri Ramanasramam has created an application called “Who Am I? Teaching” which presents the teaching of Sri Ramana Maharshi in Tamil and English as an audio book. Major Chadwick, a respected disciple of Ramana Maharshi, writes “After I had been here a day or two Bhagavan asked somebody to give me a copy of ‘Who Am I’ and told me to read it. Here is contained the essence of his teaching, and though given by him as a youth of only 21, it never needed to be changed. Bhagavan might talk all sorts of philosophy and explain various systems in answer to questions, but his teaching and instruction for sadhana were all contained in Who am I?. Everything else, as far as he was concerned, was padding or expansion for those who were not satisfied with the simplicity and straightforwardness of this little book. He had always insisted that the book should be sold so cheaply that it could be available to the poorest, and it originally cost no more than half an anna. Now this booklet is available as a free application. You can carry the Master's teaching on your cell phone and listen to it whenever you wish.
