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.
If you really understand Bhagavatam, you will become free from all of this nonsense that is making you suffer – all this envy, jealousy, hatred. All of these ideas will become completely smashed here. You have to hear it properly and then assimilate it. To purify your heart – this is Bhagavatam. And to understand Bhagavatam – this is the Sandarbhas.
