The Vedanta Philosophy includes the different branches of the Science of Yoga. Four of these have already been treated at length by the Swami Vivekananda in his works on Raja Yoga, Karma Yoga, Bhakti Yoga, and Jnana Yoga but there existed no short and consecutive sur vey of the science as a whole. It is to meet this need that the present volume has been written. In an introductory chapter are set forth the true province of religion and the full significance of the word spirituality as it is understood in India. Next follows a comprehensive definition of the term.
