Kriya Yoga is an instrument through which human evolution can be quickened. Learn the essence of this spiritual science from its greatest proponent, Paramhansa Yogananda, in his own words. Heed his vibrant call, "Awaken! Arise from dreams of littleness to the realization of the vastness within you." This is a compilation and selection of the original writings of a spiritual master whose life work was to spend over 30 years in the West as the Fountain of Life, from which countless have drunk. This volume consists of the complete 1925 versions of "The Science of Religion" and "Songs of the Soul," as well as critical excerpts from the 1946 first edition of the "Autobiography of a Yogi." Included are also other excerpts from his writings in the 1920s that are still helpful to the spiritual seekers of the world.
