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.
The whole universe is one in the Atman. That Atman when it appears behind the universe is called God. The same Atman when it appears behind this little universe, the body, is the soul. This very soul, therefore, is the Atman in us.
-Swami Vivekananda
