The eighteen chapters of the Gītā can be grouped into three sets of six chapters each. The first set focuses predominantly on karma-yoga, the second set on bhakti-yoga, and the third on jñāna-yoga. But to some extent all three topics can be found throughout all the chapters. The first chapter is introductory and doesn’t outline any specific yoga. It is titled “The Path through Despondency” (Viṣāda-yoga) because it describes Arjuna’s dejected mental-emotional state after he surveys the armies on the Battlefield of Kurukṣetra. It can be considered as a yoga, or transformational means, only in the sense that dejection itself, when it leads to self-inquiry, becomes the basis of authentic practice. In the state of dejection, one’s ordinary absorption in materialistic pursuits is slackened, and thus deliberation on God becomes a distinct possibility.
You have to understand what is service. It means you do activities for the pleasure of the person you are serving. Service is that your intention is that you want to please the person you serve. It is not that I want to gain something from it. Service itself is its own reward. If you are trying to get something then it is not really service. If it has any other motive then you can say it looks like service, but it is not really.
