All knowledge that the world has ever received comes from the mind . . ." In the quest for understanding one' s own mind, body, and soul, and to attain liberation, each man seeks spirituality as per his own means and understanding. Yoga, with its origin dating back to ancient India, has always been considered a pathway of achieving moksha. This edition combines the four paths of yoga as expounded by Swami Vivekananda in the nineteenth century. They include the three yogas mentioned in the Bhagavad Gita-- Karma Yoga, Bhakti Yoga, and Jnana Yoga-- and Raja Yoga, which is based on Maharshi Patanjali' s Yoga Sutras, and together they speak to the active, the emotional, the mystic, and the philosophical inside us. Complete with timeless universal wisdom, and not restricted to asanas and physical exercises, the yogic practices explained by Vivekananda become a way of life and hence lead to the realization of the Absolute.
