This book is a compilation of the talks on Yoga given by Swami Gnaneswarananda at Vedanta Society of Chicago, and taken down, mostly stenographically, by three of his students.  Every effort has been made to weave those notes into a whole that is both comprehensive and representative of the swami's Yoga classes.  The talks are arranged under the sections: Jnana Yoga, Raja Yoga, Bhakti Yoga, and Karma Yoga.  They first appeared serially in Vedanta Kesari, one of the main journals of the Ramakrishna Order, from 1967 through 1971.   As the title indicates, the book is primarily intended for beginners in spiritual life.  However, those who are well along the road will also find much encouragement and inspiration in it.
