This book contains seven lectures of Swami Vivekananda culled from his Complete Works. It is especially intended for those who have not time enough to go through all the yogas but wish to gain a cursory knowledge of the subject. As the title suggests, the book acquaints the readers with the subject of Self-realisation and its methods in brief.
Work a little harder at meditation and it comes. You do not feel the body or anything else. When you come out of it after the hour, you have had the most beautiful rest you ever had in your life. That is the only way you ever give rest to your system.
-Swami Vivekananda
