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.
That monk is called a man of steady wisdom when his mind is unperturbed in sorrow, he is free from longing for delights, and has gone beyond attachment, fear and anger.OPEN VERSE
The wisdom of that person remains established who has not attachment for anything anywhere, who neither welcomes nor rejects anything whatever good or bad when he comes across it.OPEN VERSE
And when this one fully withdraws the senses from the objects of the senses, as a tortoise wholly (withdraws) the limbs, then his wisdom remains established.OPEN VERSE
The objects recede from an abstinent man, with the exception of the taste (for them). Even the taste of this person falls away after realization of the Absolute.OPEN VERSE
For, O son of Kunti, the turbulent organs violently snatch away the mind of an intelligent person, even while he is striving diligently.OPEN VERSE
