KARMA YOGA - Karma means duty or responsibility. PLEASE DON'T CONFUSE KARMA YOGA WITH YOGA POSTURES.
Swami Vivekananda's speech about our responsibility to this society. According to his words,
"Karma-Yoga, is a system of ethics and religion intended to attain freedom through unselfishness, and by good works. The Karma-Yogi need not believe in any doctrine whatever. He may not believe even in God, may not ask what his soul is, nor think of any metaphysical speculation. He has got his own special aim of realising selflessness; and he has to work it out himself. Every moment of his life must be realisation, because he has to solve by mere work, without the help of doctrine or theory, the very same problem to which the Jnani applies his reason and inspiration and the Bhakta his love.
Now come to the next question: What is this work? What is this doing good to the world? Can we do well to the world? In an absolute sense, no; in a relative sense, yes. No permanent or everlasting good can be done to the world; if it could be done, the world would not be this world. We may satisfy the hunger of a man for five minutes, but he will be hungry again. Every pleasure with which we supply a man may be seen to be momentary. No one can permanently cure this ever-recurring fever of pleasure and pain. Can any permanent happiness be given to the world? In the ocean we cannot raise a wave without causing a hollow somewhere else. "
