Nishkama karma refers to work done without expectation of results or reward. One interpretation is that the soul or purpose of any action should be to remember God, while subjective perceptions of results are maya or illusion. Remembering God through namasmaran or remembrance is the most important aspect of any work, while focusing on results makes one lose sight of the true purpose, which is keeping God in mind. This interpretation can be validated through one's own experiences.
