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.
I do not want to get material life. I do not want sense-life but something higher. That is renunciation. Then, by the power of meditation, undo the mischief that has been done.
-Swami Vivekananda
