Swami Vivekananda (1863-1902) was the Hindu monk who introduced the philosophy of Yoga to the western world in the late XIX Century.

Karma Yoga (The Yoga in Action) is a mental discipline that allows a person to carry out his/her duties as a service to the entire world and a path to enlightenment.

The ebook also contains Vivekananda’s essay “The Powers of the Mind” (1900).
