Raja Yoga - Swami Vivekananda

Raja Yoga is a book by Swami Vivekananda about Raja Yoga, his interpretation of Patanjali's Yoga Sutras adapted for a Western audience. Raja Yoga contains transcripts of lectures by Vivekananda on Raja Yoga, his interpretation of Patanjali's Yoga Sutras, and a rather free translation of Patanjali's Yoga Sutras plus Vivekananda's commentaries, which also was a series of talks. It presents Vivekananda's understanding and interpretation of Patanjali's Yoga Sutras, and a selection of hathayoga teachings on the basis of the beliefs that he shared with his students.

These included elements from traditional Hinduism, but also ideas from western science, Idealism, and the Neo-Vedantic esotericism of the Brahmo Samaj and Western occultism, including mesmerism and American Harmonial religion. Vivekananda adapted traditional Hindu ideas and religiosity to suit the needs and understandings of Western audiences, who were especially attracted by and familiar with Western esoteric traditions and movements like transcendentalism and New thought. An important element in his adaptation of Hindu religiosity was the introduction of his four yogas model, which includes Raja yoga, his interpretation of Patanjali's Yoga sutras, which offers a practical means to realize the divine force within, which is central to modern Western esotericism.

The other three yogas are the classical Karma Yoga (Karma Yoga), Bhakti Yoga, and Jnana Yoga (Jnana Yoga).
