Another perspective to chapter 2

All thru Chapter 1 Krishna listens to the nervous release of tension by Arjun as a good mate.

Says nothing till Arjun's seeks help & surrenders. First Krishna encourages as a friend and scolds in 2.2. Then Arjun mentions his intent to surrender in Shlok 2.07

Let us remember that the fives senses, collect information and pass to brain.
From Body to mind & then mind seeks help from intellect.
Intellect based on past experiences gives judgement & back to mind
If mind & intellect not in agreement then confusion arises and then body reacts, trembles & sweats due to imbalance.

Arjun was confused as ego had come in : I am fighting, My relatives, the fact that he is part of Pandava and they are fighting for righteousness (PS Bheeshma & Drona had drowned their identities and merged in Kauravas army)

Surrender to Krishna : This signifies - Ego merges into intellect 

Krishna holding reigns (intellect controlling senses) & directing the Jiva

Advice starts from 2.11

Krishna explains by traditional & various logics : 

• Kshatriyas Dharma, people will condemn you 
• Then explains soul being eternal, indestructible. Soul takes birth for experience.

Explains the Stith Pragya.

Material world, senses contact objects and create desires, then anger, Raag & Dwesh or more desires and eventually delusion ....like a boat without Majhi at mercy of wind & waves....till we become a witness to the world and control our senses and be like the ocean that is so full

Rise above  all 3 (BMI) levels of dwandha ( Raag Dwesh) 

2.47 use energy on performing action. Do not dissipate energy worrying about future / result.

Sun rays all around. If focussed thru a lense can burn where the combined rays fall. Focussed efforts have bit results.

Night to usual people, is day for Yogi : 

Night is all darkness, no shapes & forms. Day is bright and forms & shapes

Yogi does not see forms & shapes 

Likes & dislikes due to past impressions, but if aware & do not dwell on them, then, one will not be swayed. Do not let the raag / dwesh overpower you.

A bit of Karam, Dhyan & Bhakti yoga are in this Chapter. Many call this the index to the Gita, as it touches or mentions what comes later.
