If Arjuna could convert warfare into Karma Yoga, then we can convert any of our duties. Duties are always moral. None of the duties are immoral. So you can convert them into spiritual practice. Internal shift is required. And time. Swami Vivekananda says, the ancient monarchs who were absolute monarchs with tremendous responsibilities and tensions and all, they found time for this philosophy. Compared to them, we have enormous amounts of time. It's just an excuse to say that we don't have time. If we want to, only five ideals, we can put 50 ideals into practice in our lives if we want.
