This text on Karma Yoga (Yoga of Action) was assembled from the transcribed talks of Sri Gurudev (Spiritual Master) Sri Swami Satchidananda and from the works of Swami Vivekananda, Swami Abedananda (Brother-monk of Swami Vivekananda), Swami Sivananda and other Saints and writers. This text is much more comprehensive than any other text on Karma Yoga. It covers all aspects of Karma Yoga with guidelines for practicing it. There are four major paths for attaining the life?s goal of Self-realization or God-realization, namely, Bhakti Yoga, Raja Yoga, Jnana Yoga and Karma Yoga. Karma Yoga is the approach to God through selfless service. It spiritualizes our day-to-day activities and service to others and by its magic touch, work becomes worship and Yoga.
