The Gita consists of eighteen chapters in total and is the dialogue between Lord Krishna and Arjuna:
1. Arjun-Visada Yoga: Arjuna requests Krishnato move his chariot between the two armies. When Arjuna sees his relatives on the opposing army side of the Kurus, he loses morale and decides not to fight.
2. Sankhya Yoga:: After asking Krishna for help, Arjuna is instructed that only the body may be killed, as he was worried if it would become a sin to kill people (including his gurus and relatives), while the eternal self is immortal. Krishna appeals to Arjuna that, as a kshatriya, his duty is to uphold the path of dharma through warfare. Krishna told Arjun the three principles, namely Dharma, Atman and the Sharira(Body).
3. Karma Yoga: Arjuna asks why he should engage in fighting if knowledge is more important than action. Krishna stresses to Arjuna that performing his duties / karma for the greater good, but without attachment to results, is the appropriate course of action. Lord Krishna emphasises that righteous action outweighs knowledge.
4. Karma -Sanyasa Yoga: Sri Krishna reveals that he has lived through many births, always teaching Yoga for the protection of the pious and the destruction of the impious and stresses the importance of accepting a guru.
5. Dnyan-Karma-Sanyasa Yoga: Arjuna asks Krishna if it is better to forgo action or to act (“renunciation or discipline of action”). Krishna answers that both ways may be beneficent, but that acting in Karma Yoga is superior.

11. Visvarupa-Darsana Yoga: On Arjuna’s request, Krishna grants him a special vision that displays his “universal form” (Viśvarūpa), a theophany of a being facing every way and emitting the radiance of a thousand suns, containing all other beings and material in existence.
