This booklet comprises of class talks given by Swami Vivekananda to an intimate audience in America. Here the subject of practical spirituality in the form of Raja Yoga is presented in a very lucid and succinct form, offering many valuable hints and directions for spiritual practice. The book is thus designed to be a precious and authoritative guide for all serious students of practical religion.
Realize your true nature. That is all there is to do. Know yourself as you are -- infinite spirit. That is practical religion. Everything else is impractical, for everything else will perish.
-Swami Vivekananda
