Synopsis 'The Arya Samaj is undoubtedly a potent spiritual ferment in the Punjab, combining what may be called a "Protestant" reformation of the secular abuses and legendary accretions of orthodox Hinduism with a Puritan simplification of life and a Roundhead insistence on the development of Indian intellectual life and thought. Of this movement and in this social service, Mr. Lajpat Rai has been long a leader. He adds a new service to us all by bringing its history, its aims and its achievement to the notice of the ever-growing English-reading public, not only in the United Kingdom and America, but also in India and Japan.'
