In chapter 2, Arjuna accepts the position as a disciple of Lord Krishna and requests the Lord to instruct him in how to dispel his lamentation and grief. This chapter is often deemed as a summary to the entire Bhagavad-Gita. Here, many subjects are explained such as: Karma yoga, Jnana yoga, Sankhya yoga and the 'Aatma' which is the soul. Predominance has been given to the immortal nature of the soul existing within all living entities and it has been described in great detail.
