Jnana yoga is called the path of knowledge, or the path of non-dualism. This yoga has become popular in the west, especially for people who wish to bypass the concept of a personal God and the excesses of organized religion.
Of special note are the series of lectures on "Practical Vedanta" found in the book. This is not a section on dry theory that doesn't relate to the world, but an active guide to integrating Vedanta into our daily lives.
Swami Vivekananda's most important teachings on Jnana Yoga were given in the West.
We also sell an Indian edition of the same title. This edition is printed in the US on better quality paper and is better edited.
