It is a very famous philosophical context of Hindu scriptures that dates back to the Bhagavad Gita. Lord Krishna described the essence of it. However, people mostly misunderstand it, even some Himalayan yogis draped in orange. My goal is to make this crystal clear, so it stays with you forever. Nishkama karma in its sense means self-less or, action without desiring the fruit of it for self gain. But Dharma always precedes Karma; everyone has a specific role in the circle of life, and fulfilling that role constitutes following one’s dharma. In most of the case anything other than you is dharma. But what about it in the modern context, if your employer is asking you to close a deal and achieve a milestone? You said, "we should focus only on the work, not the goal", and quoted the yogi’s wise words on “Nishkama karma”, yet the next day, your employer surprisingly fired you. Even lord Krishna would have seen that coming, can’t blame your employer for the same. Here is the catch: when you are in an employer and employee contract, then it is your dharma to achieve that milestone. If you have achieved that milestone and asked for nothing in return, it is Nishkama karma. It is then the dharma of your supervisor to carefully assess your contribution and propitiate the rewards. The ball is in his court, not yours. But, if you immediately go to your supervisor asking for a raise or appreciation in your upcoming appraisal it is not Nishkama anymore. Similarly, if you have given or done something for other without the expectation of fruits, then it is Nishkama karma, but if the same person goes on abusing the merit that you have bestowed upon him, which in turn affects many people, then the Dharma will come into play, in such a scenario you can even take back the gift or the blessing given, it will still be Nishkama karma. Hindu scriptures recount many stories where blessings, when misused, were revoked with harsh consequences. It will be a joy for you to recollect those stories.
