This Audiobook is an audio rendering of the book, Six Lessons on Raja Yoga, published by Advaita Ashrama, A publication branch of Ramakrishna Math, Belur Math. Â
It comprises the notes of class talks given by Swami Vivekananda to an intimate audience in the home of Mrs. Sara C. Bull, a devoted American disciple, which were preserved by her and finally printed in 1913 for private circulation among those who wanted to be benefited by them.
Of these class talks, it may be said that they present the subject of practical spirituality in a very lucid and succinct form and offer many valuable hints and directions of Sadhana, especially of Raja Yoga.
 Swami Vivekananda was the foremost to introduce Indian philosophies of Vedanta and Yoga to the Western world and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century. He was a major force in the revival of Hinduism in India, and contributed to the concept of nationalism in colonial India. Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission.
