The second chapter of the Bhagavad Gita is "Sankhya Yoga". This is the most important chapter of the Bhagavad Gita as Lord Krishna condenses the teachings of the entire Gita in this chapter. This chapter is the essence of the entire Gita. "Sankhya Yoga" can be categorized into 4 main topics - 1. Arjuna completely surrenders himself to Lord Krishna and accepts his position as a disciple and Krishna as his Guru. He requests Krishna to guide him on how to dismiss his sorrow. 2. Explanation of the main cause of all grief, which is ignorance of the true nature of Self. 3. Karma Yoga - the discipline of selfless action without being attached to its fruits. 4. Description of a Perfect Man - One whose mind is steady and one-pointed.
