Concentration and Meditation/14th Edition
No saint or sage in the history of the world has such a prolific literary output to his credit, in addition to the building up of a world-wide organization. Even dynamic political leaders have confessed often that the exigencies of administration keep them away from literary pursuits. It is only Swami Sivananda, who has been able to keep a continuous flow of spiritual literature, in spite of being busily engaged in the administration of the Divine Life Society.The secret, according to him, lies in being able to switch his mind on, at will, from one task to another, without the least difficulty and with great advantage. Sri Swami Sivananda's writings are characteristic in being free from the rigid technical nomenclature and the austere logic usually met with in texts dealing with super-mundane matters and in thus being accessible even to the most non-intellectual type of aspirants. A medico by profession, Swami Sivananda moved towards spirituality and established the Sivananda Asram at Rishikesh in the year 1934.His lucid teachings and writings attracted many and the Ashram became one of the most revered spirituality centres.Many of his disciples established their Ashrams devoting themselves to the propogation of the teachings of their master.One such, Swami Satyananda Saraswati, established the internationally famous Bihar School of Yoga and produced many master pieces on the subject like Asana Pranayama Mudra Bandha and other titles, best sellers on amazon.com
