The 3rd chapter of Bhagavad Gita expounds the philosophy of Karma Yoga- the yoga of detached action. Karma Yoga is an important stepping stone in spiritual enlightenment. This philosophy weaves spirituality in and through fruitful activities in the service of humanity. One of the prerequisites of enlightenment is mental purity. Purity can be gained only through selfless work dedicated to God and humanity. Swami Bodhananda unfolds the science, art and practice of Karma Yoga based on the third chapter of Bhagavad Gita.”
