"There is a strange idea prevalent that by merely teaching the dogmas of religion children can be made pious and moral. This is an European error, and its practice either leads to mechanical acceptance of a creed having no effect on the inner and little on the outer life, or it creates the fanatic, the pietist, the ritualist or the unctuous hypocrite. Religion has to be lived, not learned as a creed. ... But whether distinct teaching in any form of religion is imparted or not, the essence of religion, to live for God, for humanity, for country, for others and for oneself in these, must be made the ideal in every school which calls itself national. It is this spirit of Hinduism pervading our schools which — far more than the teaching of Indian subjects, the use of Indian methods or formal instruction in Hindu beliefs and Hindu scriptures — should be the essence of Nationalism in our schools distinguishing them from all others."
