This booklet published by Advaita Ashrama, a publication branch o Ramakrishna Math, Belur Math, gives us a roadmap to tune our bodies and minds and make them do what we want. Though initially written for the inmates of the hostels of Ramakrishna Mission, the value of the booklet is being increasingly understood by many people outside this fold. As all of us need to develop our lives and unfold the immense potential of our Self; this booklet finds relevance in the lives of all of us, student or otherwise.
