The Dru Bhagavad Gita continues by explaining that by acting in the wrong way, attachment is created and in chapters four and five Krishna explains that freedom comes to us by acting in the right way with wisdom and free from selfish desire, renouncing the fruits of actions.
In order for Arjuna to implement this he needs to learn to control his mind and senses and in chapter six Krishna, who knows that ones state of mind determines the quality of action begins to instruct him in the art of meditation, giving him practical techniques and methods. Now Arjuna can do something practical instead of just absorbing philosophy. Having taken him this far, Krishna decides to give Arjuna a glimpse of His divine power and who He,(Krishna) is, in a small preview of chapter eleven, and how to see His world from a different perspective in chapter seven.
