Srimad Bhagavad-Gita :
Chapter-5. ( Karma-sanyasa-yogam )
The fifth chapter begins with a doubt of Arjuna to Lord Sri Krishna.
Though this question ( doubt ) shows similarity, in the sense of the doubts raised by Arjuna in the beginning of third chapter, it is not a repetition.
In the second chapter when Arjuna heard the tattvam-s explained to him, by Lord, Arjuna could not decide and loosing his balance of mind, thought that, 'is there any place for karmam in spiritual life'.
At present his doubt is : "which one is best '1. Karma-sanyasam or 2. Karma-yogam'?
From this Lord has succeeded to convince Arjuna that to defeat Adharmam and to establish Dharmam 'Karmam' is inevitable.
We can say that Arjuna has got back his balance of mind at least by now. Arjuna now understands that wise karmam is essential for higher knowledge and for spiritual growth.
