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.
All that is real in me is God; all that is real in God is I. The gulf between God and me is thus bridged. Thus by knowing God, we find that the kingdom of heaven is within us.
-Swami Vivekananda
